The City Centre Transit Terminal in Mississauga, Ontario, Canada is the main transit hub and bus station for MiWay, the city's public transit system. The station is situated in Mississauga City Centre at the north side of Square One Shopping Centre. Prior to 2024, buses using the terminal displayed "Square One" on their destination signs.

Buses use the upper level, while access from the mall is through the lower level via a signalized crosswalk (no indoor connection), where a taxi stand and kiss and ride are located. Services provided on the upper level of the building include ticket sales, information booth, and lost and found, while washroom facilities and MiWay transit police holding cells are located on the lower level. The terminal is accessible by both elevator and escalator.

GO Transit's regional Square One Bus Terminal is located directly north, across Rathburn Road, on Station Gate Road.

The terminal opened in November 1997, replacing an overcrowded loop on the southeast side of the mall. Seventy five percent of the cost of the $6.5 million project was covered by subsidies from the Ministry of Transportation of Ontario, with the balance of funds coming from the city's capital budget. Platforms were extended east along Rathburn Road in the mid to late 2000s.

In 2015, public washrooms were renovated.

In 2016, the bus terminal was closed except the building for repairs. Buses at that time had to be boarded along Rathburn Road.

Along with MiWay buses, the terminal is served by one Brampton Transit Züm bus rapid transit route. All routes are wheelchair-accessible.
