Cattawade Slipway is a public boat launch located at Cattawade Picnic Site, off Bergholt Road, Brantham, near Manningtree (CO11 1QW), on the River Stour.

The site provides access to the tidal lower reaches of the Stour and is a popular put-in point for paddlers exploring the river toward Flatford Mill and the wider Constable Country waterway.

The picnic site and surrounding land are owned by the River Stour Trust. The slipway can be reached by taking the B1070 off the A12 shortly after crossing into Suffolk.
