Q38 (New York City bus)

The Q38 is a bus route in Queens, New York City. The route travels from the Corona and Elmhurst neighborhoods to the Forest Hills neighborhood, running in a "C" shape via the Metropolitan Avenue station in Middle Village. It runs seven days a week but does not operate overnight. Formerly privately operated by Triboro Coach Corporation, the route is now city-operated under the MTA Bus Company brand of MTA Regional Bus Operations.

The Q38 was founded as two separate routes. The Penelope Avenue route was originally started by the Affiliated Bus Transit Corporation on June 17, 1934, as the Q38, which ran from East Elmhurst to the Metropolitan Avenue station. The Eliot Avenue portion of the line was a separate Triboro Coach route, which began operating in 1940 as alternate branches of the Q45 (now the southern half of the Q47). The Eliot Avenue portion was later split into its own route, the Q45X (later the Q50). The East Elmhurst branch of the old Q38 was truncated to Forest Hills by 1948. On July 3, 1960, the Penelope and Eliot Avenue routes were combined into the current loop service, with the Q38 designation retained for the entire route. Service on Eliot Avenue will be split off into the Q14 on June 29, 2025, when operations of both routes will be taken over by the New York City Transit Authority.
