The West Blockhouse Point Beacons are three leading light beacons, they perform the same function as a lighthouse and are situated on the promontory to the west side of the entrance to Milford Haven, and lie about a mile north-east of St. Ann's Head in Pembrokeshire, Wales.

Each column carries a steel daymark painted black and white.

[1] There is also a leading light beacon on the cliff below West Blockhouse Fort, set up by Trinity House engineers in 1957.

This has a second-hand round metal lantern (ex Rame Head) which is 2 feet 7 inches (0.79 m) in diameter, supported on a bolted iron pedestal, standing on a concrete platform cantilevered from the cliffs and reached by a steeply descending flight of steps.

[1] The beacons are operated by the Milford Haven Conservancy Board and are approached via Dale then the road to St Ann's Head, turning left into Maryborough Farm Road, and then taking a right turn.
