The M1, M2, M3, and M4 are four local bus routes that operate on the Fifth and Madison Avenues Line – along 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 to 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.

The M1, M2, M3, and M4 all run between Midtown or Lower Manhattan and Upper Manhattan, while the Q32 runs from Midtown north along Fifth and Madison Avenues and east over the Queensboro Bridge to Jackson Heights, Queens. The M4 and Q32 begin at Penn Station, joining Madison Avenue at 32nd Street (northbound) and Fifth Avenue at 34th Street (southbound). Thus, all five routes are on Fifth and Madison Avenues north of 34th Street.
