Commercial Wharf slipway sits on Sutton Harbour on the River Plym in Plymouth's historic Barbican district. The 10-metre-wide cobbled slipway provides water access at most states of the tide and is free for public use.

It is suited to launching sailing dinghies, small craft, and canoes.

Access is off Madeira Road, either directly via Commercial Wharf or through the adjacent Elphinstone car park — note that both approach routes are narrow, and the Elphinstone route has limited overhead clearance due to overhanging trees.

Pay-and-display parking is available at Elphinstone car park, with public toilets nearby at the entrance to the Elphinstone dinghy park. A range of food and retail outlets can be found close by in the Barbican.
