Anacostia Neighborhood Library

Southeast (SE or S.E.) is the southeastern quadrant of Washington, D.C., the capital of the United States, and is located south of East Capitol Street and east of South Capitol Street. It includes the Capitol Hill and Anacostia neighborhoods, the Navy Yard, the Joint Base Anacostia-Bolling (JBAB), the U.S. Marine Barracks, the Anacostia River waterfront, Eastern Market, the remains of several Civil War-era forts, historic St. Elizabeths Hospital, RFK Stadium, Nationals Park, and the Congressional Cemetery. It also contains a landmark known as "The Big Chair," located on Martin Luther King Jr. Avenue. The quadrant is split by the Anacostia River, with the portion that is west of the river sometimes referred to as "Near Southeast". Geographically, it is the second-smallest quadrant of the city.

Anacostia High School is a public high school in Anacostia, in the Southeast quadrant of the District of Columbia.

Fort Stanton was a Civil War-era fortification constructed in the hills above Anacostia in the District of Columbia, USA, and was intended to prevent Confederate artillery from threatening the Washington Navy Yard. It also guarded the approach to the bridge that connected Anacostia (then known as Uniontown) with Washington. Built in 1861, the fort was expanded throughout the war and was joined by two subsidiary forts: Fort Ricketts and Fort Snyder. Following the surrender of the Army of Northern Virginia, it was dismantled and the land returned to its original owner. It never saw combat. Abandoned after the war, the site of the fort was planned to be part of a grand "Fort Circle" park system encircling the city of Washington. Though this system of interconnected parks never was fully implemented, the site of the fort is today a park maintained by the National Park Service, and a historical marker stands near the fort's original location.

The Frederick Douglass National Historic Site, administered by the National Park Service, is located at 1411 W Street, SE, in Anacostia, a neighborhood east of the Anacostia River in Southeast Washington, D.C. United States. Established in 1988 as a National Historic Site, the site preserves the home and estate of Frederick Douglass, one of the most prominent African Americans of the 19th century. Douglass lived in this house, which he named Cedar Hill, from 1877–1878 until his death in 1895. Perched on a hilltop, the site offers a sweeping view of the U.S. Capitol and the Washington, D.C., skyline. In 2017 the site was used to represent Washington, D.C., on its America the Beautiful quarter.

The Washington Yacht Club is a motorboating club on the Anacostia River in Washington, D.C. Established in 1910 as an all-white organization, the club was integrated in the 1970s, prompting a turnover to predominantly African American membership. In addition to serving as a marina and social club, the Washington Yacht Club has advocated for the environmental protection of the Anacostia, which at one point was one of the most polluted rivers in the United States. The group's clubhouse and surrounding property were listed on the National Register of Historic Places in 2020.

Honfleur Gallery located on Good Hope Road in the Anacostia Historic District neighborhood of Washington, D.C., is a gallery that was established in January 2007 by the Action to Rehabilitate Community Housing group. The art gallery opened amid concerns of whether an art gallery was what the neighborhood needed. By 2014, seven years after its formal opening, local residents were apparently still divided over the impact or reason for the art gallery in the neighborhood. "The neighborhood, long synonymous with urban blight, is an unconventional choice for a swanky art gallery," asserted a 2014 Washington Post article on the gallery.

Park Naylor is a residential neighborhood located in southeast Washington, D.C. It takes its name from its northern and eastern borders, Naylor Road and Fort Stanton Park. Park Naylor's other boundaries are Minnesota Avenue to the west, and Good Hope Road SE to the south. Also see article on Anacostia.

Skyland is a neighborhood in Southeast Washington, D.C. It is bounded by Good Hope Road to the northeast, Alabama Avenue to the southeast, and Fort Stanton Park to the south and west. It is part of Ward 8. Also see article on the Anacostia neighborhood. The District is in the midst of redeveloping the 18-acre (73,000 m2) Skyland Shopping Center at Alabama Avenue and Naylor Road, SE in Ward 7 into a mixed-used town center. The District is working with the Rappaport Cos. and the William S. Smith Cos. on a master plan for the site. Initial plans for Skyland Town Center call for more than 320,000 square feet (30,000 m2) of retail space—a combination of high-quality, large format national-brand retailers and neighborhood serving shops and restaurants. The project will also include 420 to 470 units of housing, about 80 percent of the units will be condos and 20 percent will be apartments. Several outstanding legal issues associated with the project have complicated the development process, but the District is working closely with the development team and its architects, Torti Gallas + Partners, to accelerate the pre-development work so the project moves on a parallel track with the legal process. The development team expects to have its master plan completed and a Planned Unit Development (PUD) application filed with the Zoning Commission by the spring of 2008. The District and development team are negotiating the business terms of their agreement. The DC Council has already approved a Tax Increment Financing (TIF) package to provide gap financing for the project. Skyland is within the Good Hope neighborhood and borders Hillcrest to the east and Naylor Gardens to the southeast.

MahoganyBooks is an independent bookstore specializing in works by the African diaspora. It was established as an online store in 2007 by Derrick and Ramunda Young.

Fort Stanton is a residential neighborhood in Southeast Washington, D.C. It is bounded by Erie St SE. to the north, Suitland Parkway to the south, 16th St. SE to the west, and 19th Pl SE to the east. The neighborhood is named after the nearby civil War defense Fort Stanton. Fort Stanton is part of Ward 7, represented by Vince Gray. Fort Stanton is situated between the neighborhoods of Anacostia, to the north, Barry Farm to the west, Garfield Heights to the East, and Douglass to the south. The nearby Anacostia Community Museum is located in Fort Stanton as well as the nearby Fort Stanton Recreation Center and Fort Stanton Pool.

The John Philip Sousa Bridge, also known as the Sousa Bridge and the Pennsylvania Avenue Bridge, is a continuous steel plate girder bridge that carries Pennsylvania Avenue SE across the Anacostia River in Washington, D.C., in the United States. The bridge is named for famous United States Marine Band conductor and composer John Philip Sousa, who grew up near the bridge's northwestern terminus. The first bridge at this location was constructed in 1804, but burned by United States armed forces in 1814 during the War of 1812. It was replaced in 1815, but the bridge burned to the waterline in 1846. The rapid growth of residential developments east of the Anacostia River led to the construction of a narrow, iron girder bridge in 1890. This bridge led to even swifter economic and residential development of the area. Efforts to replace the 1890 bridge with a modern structure began in 1931, but were not successful until 1938. The downstream (southern) span opened on December 9, 1939, to great fanfare. The upstream span was completed in December 1940 and opened on January 18, 1941. The Sousa Bridge has a partial interchange with the Barney Circle traffic circle at its northwestern end, and a partial interchange with Anacostia Freeway at its southeastern terminus. A major battle over building an Inner Loop Expressway in the District of Columbia occurred in the 1950s and 1960s. This led to the partial construction of Interstate 695 from Interstate 395 to Barney Circle, but political battles over the wisdom of further construction led to cancellation of the remaining highway—leaving Barney Circle and the northern approaches to the Sousa Bridge partially deconstructed. An attempt to build the remainder of Interstate 695 (the "Barney Circle Freeway") in the 1990s also failed. In 2010, the District of Columbia decommissioned the portion of Interstate 695 leading to Barney Circle and the Sousa Bridge, and began rebuilding the circle and approaches.

The Pennsylvania Avenue Bridge was a crossing of the Anacostia River in Washington, DC at the site of the present John Philip Sousa Bridge. It was constructed in 1890 and demolished around 1939.
