Barley Mow Slipway is a boat launch site on the Basingstoke Canal in Hampshire, located off Sprat's Hatch Lane near Dogmersfield, close to the Barley Mow pub.

The slipway provides a straightforward entry point to the canal, suitable for canoes, kayaks, paddleboards, and larger craft. Free parking is available at the adjacent car park.

The site is a popular starting point for trips eastward along the canal, with Odiham Castle a common destination roughly nine miles away.

A day licence fee is required to use the canal and can be paid online, by phone, or in person at the Basingstoke Canal Authority's Canal Centre in Mytchett.
