The Sidney class consisted of two roll-on/roll-off ferries, Queen of Sidney and Queen of Tsawwassen, built for the British Columbia Ferry Corporation in service from 1960 to 2008. The design for the ships was based on the ferry MV Coho with changes made to accommodate loading of vehicles through the bow of the vessel. Both vessels serviced different routes throughout their service lives.

British Columbia Ferry Services Inc., operating as BC Ferries (BCF), is a former provincial Crown corporation, now operating as an independently managed, publicly owned Canadian company.
