The Shreveport Area Transit System, commonly known as SporTran, is a public transportation bus system based in Shreveport, Louisiana, United States. It runs bus routes in Shreveport and Bossier City, Louisiana. All bus routes converge at the Intermodal Facility near Downtown Shreveport.

SporTran provides public transportation in the form of buses and lift vans. SporTran is one of the oldest public transportation systems in the south. SporTran has been in continual service for over 125 years with only one interruption due to the strike of 1957.

SporTran operates seven days a week on 17 bus routes from 6:00 a.m. to 1:00 a.m., with shorter operations on the weekends. As of 2006, SporTran operates night service on five routes (mostly supplementing daytime service after end of service) between 8:00 p.m. and midnight Monday through Saturday with no service on Sundays.

SporTran has a fleet of over 50 buses equipped to handle all passengers, including those with disabilities. Their newest buses are equipped with the emission reduction systems and an experimental dual-fuel (Hybrid) bus was placed in service in 2005.

No fares are charged within city limits since 2020, but will apply if outside.
