The DeKalb Avenue Line is a public transit line in Brooklyn and Queens, New York City, running mostly along DeKalb Avenue, as well as eastbound on Lafayette Avenue (as part of a one-way pair), between Downtown Brooklyn and Ridgewood, Queens. Originally a streetcar line, it is now the B38 DeKalb/Lafayette Avenues bus route, operated by the New York City Transit Authority. At its east end, after crossing into Queens, the line turns southeast on Seneca Avenue and ends just short of Myrtle Avenue, at Catalpa Avenue. A branch runs northeast on Stanhope Street to Linden Hill Cemetery.
