23 Beekman Place, also the Paul Rudolph Apartment & Penthouse, is an apartment building between 50th and 51st streets in the Turtle Bay neighborhood of Manhattan in New York City. Built c. 1869 as a five-story brownstone residence, it was substantially redesigned in the late 20th century by Paul Rudolph, an American architect and one-time dean of Yale University. It is one of the few known projects Rudolph designed in the city. The house is part of a secluded residential enclave surrounding Beekman Place. It consists of the original brownstone residence, along with a four-story steel skeletal penthouse with concrete wall panels, which is cantilevered slightly over the street. The rear walls contain full-width windows with East River views, while the interiors contain high ceilings and open floor plans. Throughout his occupancy at the building, from the 1960s to 1990s, Rudolph constantly adjusted the interior layout. The penthouse originally received negative feedback from neighbors, who expressed concerns that it would draw excessive attention to the area and that it would block their own views of the river. The building was originally a brownstone along with the other structures in the area. In the first half of the 20th century, it was occupied by actress Katharine Cornell and director and producer Guthrie McClintic, who were married. Starting in 1961, Rudolph leased a fourth-story apartment at 23 Beekman Place, and he ultimately bought the entire building outright in 1976. Following that, Rudolph redeveloped the building from 1977 to 1982, constructing the steel penthouse above the existing masonry apartments. After Rudolph died in 1997, the building was sold to the Boyd family and then to Steven Campus, who both renovated the interior. The New York City Landmarks Preservation Commission designated the house as a landmark in 2010.

The Beekman Tower had been built for the Panhellenic Association's New York chapter as a club and hotel for women in college sororities. However, due to a lack of patronage, it was opened up to non-sorority women and to men by the mid-1930s. It was later converted into a hotel and then corporate apartments. The Beekman Tower contains a design with numerous setbacks, chamfers at its corners, and a massing that abuts onto the boundaries of its lot. Its sculptural ornamentation was designed by Rene Paul Chambellan in the Art Deco style with Gothic influences. In 1998, the New York City Landmarks Preservation Commission made the building an official city landmark.
