Trinidad is a neighborhood located in Ward 5, in the northeast quadrant of Washington, D.C., and is a largely residential area. Bounded by West Virginia Avenue NE, Florida Avenue NE, Mount Olivet Road NE, and Bladensburg Road NE

Trinidad is to the east of West Virginia Avenue, north of Florida Avenue, and west of Bladensburg Road. To the north of Trinidad is the more industrial neighborhood of Ivy City. To the west is Gallaudet University and the Florida Market (D.C.'s wholesale food district, also called the Capital City Market or more recently Union Market). To the east lies Carver Langston. To the south of Trinidad is Old City, so named because it was part of Pierre L'Enfant's original plan for the city, and generally referred to as either Near Northeast or Capitol Hill North. Located immediately south of Trinidad is the H Street Corridor. The eastern portion of the H Street Corridor is sometimes referred to as the Atlas District, part of a neighborhood branding campaign centered on the revitalized Atlas Theater.

The area got its name from 19th-century speculator James Barry, who had once lived on the Caribbean island of Trinidad. A street in the neighborhood bears the name of Trinidad Avenue NE.

The land passed to and from the Corcoran family, who used it as a country estate, to Columbian College, which later became George Washington University, and then to the Washington Brick Machine Company. The brickworks intended to excavate clay from the land, but not needing all of the land, began selling off parcels, and, in the late 19th century, the first houses in southern Trinidad were built.

The American League Park was located at the corner of Florida Ave NE and Trinidad Avenue NE from 1901 to 1904. It was home to the Washington Senators

The first two blocks north of Florida Avenue feature classic Victorian rowhouses similar to those in nearby Capitol Hill. Further north, many of the row houses are built in a flat porch-fronted style (similar to craftsman style) that gained popularity during the 1920s. Northern portions of Trinidad were developed later, some parts as late as the 1940s.
