Select Bus Service (SBS; stylized on the buses as +selectbusservice) is a brand used by the Metropolitan Transportation Authority (MTA)'s Regional Bus Operations for bus rapid transit service in New York City. SBS began service in 2008 in order to improve speed and reliability on long, busy corridors.

SBS routes use vehicle-segregated, camera-enforced bus lanes; sidewalk extensions for bus stops; relatively long distances between stops; vehicular turn restrictions along corridors; and next-bus travel information screens. The first route was the Bx12 along Fordham Road and the Pelham Parkway; as of January 2019, eighteen SBS routes run along seventeen corridors. Twenty-one more routes are proposed through 2027. However, in summer 2018, the MTA announced that it was considering delaying the implementation of SBS routes outside Manhattan until 2021 because of the city's upcoming bus-network redesign.
