List of bus routes in Suffolk County, New York

Suffolk County Transit operates a number of bus routes in Suffolk County, New York, United States; a few in the town of Huntington are operated by Huntington Area Rapid Transit. The Villages of Patchogue and Port Jefferson, also have had their own local jitney bus routes, although budget cuts have forced Port Jefferson to take its buses out of service. Some of them are the direct descendants of streetcar lines (see List of streetcar lines on Long Island). No routes operate on Sundays except where noted.

This table gives details for the routes that service Suffolk County primarily. For details on routes that run into Suffolk County but do not service it primarily, see:
