Sovereign Wharf is a small marina situated on the Oxford Canal in Banbury, Oxfordshire, offering long-term and visitor moorings for narrowboats.

The site on Compton Road provides gated, secure access with on-site car parking and direct oversight from the proprietor, giving it a more personal atmosphere than larger marinas.

Canal services available at the wharf include pump-out, Elsan disposal, Calor gas, diesel, water, mains electric, and a chandlery. The site is also a member of British Marine.
