Blue Bridge Slipway is a public boat launch located at the bottom of Blue Bridge Lane in York, at the entrance to the Foss Basin where the River Foss meets the River Ouse.

It is listed by the City of York Council as one of the public slipways serving the River Ouse area. The slipway sits near Rowntrees Park and provides access to both the Ouse and the lower Foss.

The River Foss itself runs approximately 19½ miles from its source near Newburgh Prior to this confluence point in York.

Boaters should note that passage on the River Foss requires advance booking, and maximum vessel dimensions apply for navigation beyond the slipway.
