The '''S Shuttle''' is a [[light rail]] service on the [[Muni Metro]] system in [[San Francisco, California]]. The service began in 2001 as the '''S Castro Shuttle''', an effort to reduce crowding at [[Castro station]]. It was briefly discontinued in 2007 when the [[T Third Street]] line was opened. Service was extended to [[St. Francis Circle station]] in 2013, but cut back to [[West Portal station]] in 2016. From 2020 to 2024, the shuttle ran as a full-time service as part of a reconfiguration of Muni Metro service.<ref name="aug22" />

The designation of S Shuttle is also given to trains at other hours and locations, most commonly to those which run service before and after [[San Francisco Giants]] and [[Golden State Warriors]] games to provide additional capacity to [[Oracle Park]] and [[Chase Center]] respectively.
