Yale University is a private Ivy League research university in New Haven, Connecticut. Founded in 1701, Yale is the third-oldest institution of higher education in the United States and one of the nine colonial colleges chartered before the American Revolution.The Collegiate School (Yale's original name) was established in 1701 by Congregationalist clergy of the Connecticut Colony. Originally restricted to instructing ministers in theology and sacred languages, the school's curriculum expanded, incorporating humanities and sciences by the time of the American Revolution. In the 19th century, the college expanded into graduate and professional instruction, awarding the first PhD in the United States in 1861 and organizing as a university in 1887. Yale's faculty and student populations grew rapidly after 1890 due to the expansion of the physical campus and its scientific research programs. Today, Yale is organized into fourteen constituent schools, including the original undergraduate college, the Yale Graduate School of Arts and Sciences and Yale Law School. While the university is governed by the Yale Corporation, each school's faculty oversees its curriculum and degree programs. In addition to a central campus in downtown New Haven, the university owns athletic facilities in western New Haven, a campus in West Haven, and forests and nature preserves throughout New England. As of 2021, the university's endowment was valued at $42.3 billion, the third largest of any educational institution. The Yale University Library, serving all constituent schools, holds more than 15 million volumes and is the third-largest academic library in the United States. Student athletes compete in intercollegiate sports as the Yale Bulldogs in the NCAA Division I Ivy League conference. As of October 2020, 65 Nobel laureates, five Fields medalists, four Abel Prize laureates, and three Turing Award winners have been affiliated with Yale University. In addition, Yale has graduated many notable alumni, including five U.S. presidents, 10 Founding Fathers, 19 U.S. Supreme Court Justices, 31 living billionaires, 54 college founders and presidents, many heads of state, cabinet members and governors. Hundreds of members of Congress and many U.S. diplomats, 78 MacArthur Fellows, 263 Rhodes Scholars, 123 Marshall Scholars, 81 Gates Cambridge Scholars, 102 Guggenheim Fellows and nine Mitchell Scholars have been affiliated with the university. Yale's current faculty include 67 members of the National Academy of Sciences, 55 members of the National Academy of Medicine, 8 members of the National Academy of Engineering, and 187 members of the American Academy of Arts and Sciences.

Steinbach Hall, also known as the John Pitkin Norton House, is a historic building on the campus of Yale University in New Haven, Connecticut, United States.

Hillhouse Avenue is a street in New Haven, Connecticut, famous for its many nineteenth century mansions, including the president's house at Yale University. Both Charles Dickens and Mark Twain have described it as "the most beautiful street in America." Much of the avenue is included in the Hillhouse Avenue Historic District, which extends to include houses on adjacent streets.

The Osborn Memorial Laboratories in New Haven, Connecticut were built in 1913 as the home for biology at Yale University. In the past, they contained both zoology and botany, in the two wings on Sachem Street and Prospect Street (address: 165 Prospect St.). They sit at the base of Sachem's Woods: the original site of Highwood, the mansion of James Abraham Hillhouse. This area is now known as Science Hill and is the site of Kline Biology Tower, Sage Hall (Yale School of Forestry and Environmental Studies), and chemistry and physics buildings. The building sits across Prospect Street from Ingalls Rink and across Sachem from the former location of the Yale School of Management. It was designed by the architect Charles C. Haight, who also designed buildings of the original Columbia University campus on the current site of Rockefeller Center. Osborn Memorial Laboratories is an entirely masonry structure, down to the sub-basement of unfinished brickwork. Its main arch was once a covered entry for carriages. It contained a library over that same arch, with a faux sky ceiling, now a conference room, and a series of laboratories. The laboratories and offices have been reconfigured many times. Now the first floor and basements are set aside for teaching, the second, third and fourth for research, and the fifth for special facilities on the Sachem Wing, laboratories on the Prospect Wing (where once there was a herbarium). The towers are no longer actively occupied. Work in these laboratories includes that of Joshua Lederberg, G. Evelyn Hutchinson, and others. The main department in the building is now the Yale Department of Ecology and Evolutionary Biology.

The Peabody Museum of Natural History at Yale University (also known as the Yale Peabody Museum of Natural History or the Yale Peabody Museum) is one of the oldest, largest, and most prolific university natural history museums in the world. It was founded by the philanthropist George Peabody in 1866 at the behest of his nephew Othniel Charles Marsh, an early paleontologist. The museum is best known for the Great Hall of Dinosaurs, which includes a mounted juvenile Brontosaurus and the 110-foot-long (34 m) mural The Age of Reptiles. The museum also has permanent exhibits dedicated to human and mammal evolution; wildlife dioramas; Egyptian artifacts; local birds and minerals; and Native Americans of Connecticut. As of April 2023, the Peabody Museum is closed for its "first comprehensive renovation in 90 years"; it is slated to reopen in "early 2024". During the closure, some public programming has continued on campus or online.

Kline Biology Tower is a skyscraper in New Haven, Connecticut. The building is home to the Yale University Department of Biology and is currently the tallest building on the Yale campus and the fourth-tallest building in New Haven. It was the tallest building in the city from 1966 to 1969, and was designed by Philip Johnson, who also designed the nearby—and architecturally related—Kline Geology and Chemistry Laboratories.

Science Hill is an area of the Yale University campus primarily devoted to physical and biological sciences. It is located in the Prospect Hill neighborhood of New Haven, Connecticut. Originally a 36-acre residential estate known as Sachem's Wood, it was purchased by Yale in 1910 as a land bank. To expand the former Sheffield Scientific School, the hill was allocated to large science laboratories and the main buildings of the Yale School of Forestry & Environmental Studies. Several laboratory buildings were completed in the 1910s, but most of the campus was completed during the build-up of scientific research after World War II.

Yale School of the Environment (YSE) is a professional school of Yale University. It was founded to train foresters, and now trains environmental students through four 2-year degree programs (Master of Environmental Management, Master of Environmental Science, Master of Forestry, and Master of Forest Science), two 10-month mid-career programs, and a 5-year PhD program. Still offering forestry instruction, the school has the oldest graduate forestry program in the United States. The school changed its name to the Yale School of the Environment in July 2020. It was previously the Yale School of Forestry & Environmental Studies.

The Cowles Foundation for Research in Economics is an economic research institute at Yale University. It was created as the Cowles Commission for Research in Economics at Colorado Springs in 1932 by businessman and economist Alfred Cowles. In 1939, the Cowles Commission moved to the University of Chicago under Theodore O. Yntema. Jacob Marschak directed it from 1943 until 1948, when Tjalling C. Koopmans assumed leadership. Increasing opposition to the Cowles Commission from the department of economics of the University of Chicago during the 1950s impelled Koopmans to persuade the Cowles family to move the commission to Yale University in 1955 where it became the Cowles Foundation.As its motto Theory and Measurement implies, the Cowles Commission focuses on linking economic theory to mathematics and statistics. Its advances in economics involved the creation and integration of general equilibrium theory and econometrics. The thrust of the Cowles approach was a specific, probabilistic framework in estimating simultaneous equations to model an economy. Its ultimate goal in doing so was to gain policy insight. The Cowles approach structured its models from a priori economic theory. One of its main contributions was in exposing the bias of ordinary least squares regression in identifying coefficient estimates. Consequently, Cowles researchers developed new methods such as the indirect least squares, instrumental variable methods, the full information maximum likelihood method, and the limited information maximum likelihood method. All of these methods used theoretical, a priori restrictions. According to an article by Carl F. Christ, the Cowles approach was grounded on certain assumptions: 1. simultaneous economic behavior; 2. linear or logarithmic equations and disturbances; 3. systematic, observable variables without error; 4. discrete variable changes as opposed to continuous; 5. a priori determination of exogeneity and endogeneity; 6. the existence of a reduced form; 7. independence of the explanatory variables; 8. a priori identified structural equations; 9. normally distributed disturbances with zero means, finite and constant covariances, a nonsingular covariance matrix, and serial independence; 10. a dynamically stable system of equations.Several Cowles associates have won a Nobel Memorial Prize in Economic Sciences for research done while at the Cowles Commission. These include Tjalling Koopmans, Kenneth Arrow, Gérard Debreu, James Tobin, Franco Modigliani, Herbert A. Simon, Joseph E. Stiglitz, Lawrence Klein, Trygve Haavelmo, Leonid Hurwicz and Harry Markowitz. The Cowles Foundation is located at 30 Hillhouse Avenue, New Haven, Connecticut.

The Whitney and Betty MacMillan Center for International and Area Studies at Yale, commonly known as the MacMillan Center, is a research and educational center for international affairs and area studies at Yale University. It is named after Whitney MacMillan and his wife Betty.

The Yale Jackson School of Global Affairs (formerly the Yale University Jackson Institute for Global Affairs) is a professional school of Yale University that specializes in global affairs. Based in New Haven, Connecticut, the school's mission is to "inspire and prepare Yale students for global leadership and service." It was established in 2010 and offers degrees for both undergraduate and graduate levels and includes the following programs: the Kerry Initiative, the Global Health Studies Program, the Yale World Fellows, and the Leitner Program on Effective Democratic Governance. It also hosts the Johnson Center for the Study of American Diplomacy. As of 2022, the school is led by dean James A. Levinsohn, Charles W. Goodyear Professor in Global Affairs. The Jackson Institute transitioned to a professional school in 2022. It is the first new Yale professional school created since 1976.

The William H. Taft Mansion is a historical site located at 111 Whitney Avenue in New Haven, Connecticut, United States. It was built in 1870. It is known as the Taft Mansion because U.S. President William Howard Taft owned it for a period around the time of World War I, although he may never have lived in it. In 1920 it was famously burgled by Carl Panzram, in revenge for Taft sentencing him to three years in prison at Fort Leavenworth. After selling what he had stolen, he went on a further crime spree which often included shooting his victims with a gun he stole from the house. Taft owned the house until 1921.In 2014, the William F. Buckley Jr. Program at Yale University relocated to the mansion with an option to purchase it. The location across the street from the Peabody Museum is particularly apt for the group, as Taft was both a Republican and a Yale graduate.
