Regina Transit is the public transportation agency operated by the City of Regina, Saskatchewan, Canada. It is the oldest public transit system in Saskatchewan and has been city-owned since its inception.

Regina Transit's roots go back to July 28, 1911 (as the Regina Municipal Railway)^[4] with streetcar operations, originally on ten miles (16 km) of track, growing to 20 miles (32 km) in the early 1930s. The "Dirty Thirties" saw huge deficits resulting in major cut-backs in service. With a shortage of gasoline and steel during World War II, streetcar ridership grew dramatically. The 32 streetcars used in 1945 carried 9,000,000 more passengers than they did in 1940. An important event in the system's history was a fire in its "bus barn" on January 23, 1949, that destroyed 17 trolley coaches, nine gasoline buses, five steel streetcars and nine wooden cars. On September 5, 1950, The last streetcar made its final run through the streets of Regina and the Regina Municipal Railway became the Regina Transit System. Regina Transit provided trolley bus service from 1947 to 1966 using Canada Car and Foundry Brill trolley buses. Since 1955, its preferred transit fleet has been buses because their freedom from overhead lines makes them suitable for detours and charters. An innovation in the early 1970s was its Telebus service, which used a telephone/radio dispatching system to send buses to individual homes. This service ended in the early 1980s because of its high cost.^[1] In 2008 Regina Transit adopted three new express route centred on the university, cutting bus trip time by up to 20 minutes. On April 10, 2013, the city of Regina approved a major route network change.

Regina Transit's fleet consists mostly of Nova Buses, with a few Vicinity operating on less-busy routes. As of 2014, all buses in the Regina Transit fleet are at least partially low-floored, as all high-floor buses were retired around that time.^[9]

Regina Transit operates a charter bus service and a 33-fleet paratransit service for residents who cannot use the regular transit system. Regina Transit Services has been working with the Saskatchewan Human Rights Commission to improve accessibility and inclusivity of public transportation since 2013. The SHRC recognized the work of the City of Regina in 2016. Part of that work includes the introduction of low-floor accessible buses and installation of audible stop announcements. Regina Transit continues to improve the accessibility of its services.^[11]
