Fambridge Yacht Haven is a marina situated on the north bank of the River Crouch in Essex, approximately 6 nautical miles upriver from Burnham on Crouch.

The marina lies within Stow Creek, which is accessible at most states of the tide depending on vessel draft. Vessels approaching from downriver should look for the Stow Post, a special mark at the mouth of the creek on the starboard side.

The haven offers both swinging moorings and pontoon berths, with water and electricity available on the pontoons. Boatyard services are also on site.

The facility sits close to the village of North Fambridge, with South Fambridge visible on the opposite bank of the Crouch.
