The B54 is a bus route on Myrtle Avenue in Brooklyn, New York City. The line travels between Downtown Brooklyn in the west and Myrtle–Wyckoff Avenues station in the east. The B54 operates from MTA New York City Bus's Fresh Pond Depot in Ridgewood, Queens. The route serves only the section of Myrtle Avenue within Brooklyn; the section within Queens is served by the Q55 bus.

The B54 replaced the Myrtle Avenue Line, the first streetcar line in Brooklyn, which was built by the Brooklyn City Railroad and opened in 1854. This line initially served the entirety of Myrtle Avenue with horse cars. They were replaced with electric trolleys by July 1893, and then by the two city-owned bus routes on July 17, 1949. The Myrtle Avenue Line is distinct from the BMT Myrtle Avenue Line, which is a separate subway line that also operates along a portion of Myrtle Avenue in Bushwick, Brooklyn. Until 1969, the BMT line also ran on elevated tracks above the entire Brooklyn section of Myrtle Avenue.
