List of bus routes in the Bronx

The Metropolitan Transportation Authority (MTA) operates a number of bus routes in the Bronx, New York, United States. Many of them are the direct descendants of streetcar lines (see list of streetcar lines in the Bronx). All local buses are operated by the New York City Transit Authority, except for the Bx23, which is operated by the MTA Bus Company.

Eight Metro-North Railroad feeder routes are operated by Logan Bus Company to and from the Riverdale and Spuyten Duyvil stations, under contract with the brand name of Hudson Rail Link. See Hudson Rail Link for more details.

Proposed bus route changes
As part of the MTA's 2017 Fast Forward Plan to speed up mass transit service, a draft plan for a reorganization of Bronx bus routes was proposed in draft format in June 2019, with a final version published in October 2019. Many of the draft proposals were not included in the final version. These changes were set to take effect in mid-2020. Due to the COVID-19 pandemic, the implementation of the bus redesign was postponed to mid-2022.

If a route is not being changed, it will not be listed here. Changes to the M100, M125, Q44, and Q50 routes are not listed here. For a list of changes to the M100 and M125 bus routes, see. For a list of changes to the Q44 and Q50 bus routes, see.
