Hazelbeach is a boat ramp and slipway facility on Pennar Mouth, part of the Milford Haven Waterway in Pembrokeshire, Wales.

A seasonal pontoon is deployed near the slipway between 1 April and 1 October, typically made up of six sections with a hammerhead on the outermost end.

The pontoon serves recreational vessels for passenger and equipment drop-off and pick-up, and is also popular for informal activities such as crabbing and angling. The nearby Ferry Inn makes Hazelbeach a convenient stop for waterborne visitors.

The area also supports a number of registered moorings managed under a voluntary control arrangement.
