The list of routes of City of Buffalo streetcars lists all lines of historic Buffalo street car systems. Streetcars in Buffalo have declined in recent decades and been replaced by the car, and to a lesser extent, light rail.

After the amalgamation of a number of streetcar companies during the early start of the 20th century, the International Railway Company began assignment of route numbers to virtually all of its routes it operated. Some truncated versions (such as "Abt" for Abbott Road, and "Bst" for Best Street) remained, but were slowly assigned numbers, similar to the current route numbers used in today's NFTA Metro routes.

1935 (late-depression years) The Green Guide of Buffalo and Vicinity, 1935 Edition, Empire State News Corp.

Shortly after 1935, major changes were becoming evident, with elimination of streetcar service on virtually all west-side lines, including (from west to east) 5-Niagara, 3-Grant, 7-Hoyt and 20-Elmwood streetcars, and (from north to south) 10-West Utica, and 22-Connecticut streetcars.

Post-1940, the only streetcar that crossed Main Street, continuing westbound, was the 23-Fillmore/Hertel car operating between South Park Avenue in South Buffalo and Tonawanda Street using a loop over Tonawanda, Grace, Niagara and Hertel.
