The St. Clair Carhouse (also known informally as the Wychwood Carhouse) was a streetcar facility in Toronto, Ontario, Canada. It was located south of St. Clair Avenue on a parcel of land bounded by Wychwood Avenue on the east, Benson Avenue on its north side and Christie Street on the west side. It was opened by the Toronto Civic Railways in 1913, taken over by the Toronto Transportation Commission in 1921 and closed by its successor, the Toronto Transit Commission, in 1998. The carhouse was subsequently transformed into a community centre called the Wychwood Barns.
