The M1, M2, M3, and M4 are four local bus routes that operate the Fifth and Madison Avenues Lines – along the one-way pair of Madison and Fifth Avenues in the Manhattan borough of New York City. Though the routes also run along other major avenues, the majority of their route is along Madison and Fifth Avenues between Greenwich Village and Harlem.

The routes are the successors to the New York and Harlem Railroad's Fourth and Madison Avenues Line, which began operations in 1832 as the first street railway in the world, and several lines of the Fifth Avenue Coach Company, a bus operator that started running on Fifth Avenue in 1886.
