Bedford Avenue is the longest street in Brooklyn, New York City, stretching 10.2 miles (16.4 km) and 132 blocks, from Manhattan Avenue in Greenpoint south to Emmons Avenue in Sheepshead Bay, and passing through the neighborhoods of Williamsburg, Bedford-Stuyvesant, Crown Heights, Flatbush, Midwood, Marine Park, and Sheepshead Bay.

Williamsburg is a neighborhood in the New York City borough of Brooklyn, bordered by Greenpoint to the north; Bedford–Stuyvesant to the south; Bushwick and East Williamsburg to the east; and the East River to the west. It was an independent city until 1855, when it was annexed by Brooklyn; around that time, the spelling was changed from Williamsburgh to Williamsburg.
