Trinidad is a neighborhood in Northeast Washington, DC, in the city's fifth ward.  Bordered to the north by Mount Olivet Cemetary, to the east by the National Arboretum and Bladensburg Road, to the west by Gallaudet University, it is a largely residential area with quiet, tree lined streets and a mix of single-family homes and two-story apartment buildings.

The land on which Trinidad stands originally belonged to a member of the Corcoran family, and it later passed to George Washington University before being sold to one of the brickworks that once operated in the area. The brickworks intended to excavate clay from the land. Realizing that they did not need all of the land, the brickworks began selling off parcels, and, in the late 1800s/early 1900s, the first houses in Trinidad were built. Many of the rowhowsed are flat porch-fronted houses (similar to craftman style, except in a rowhouse) built in a style that gained popularity during the 1920s. The area is predominantly African American, historically working class and has a substantial deaf student population from nearby Gallaudet University.
