The boat ramp at Hamelin Bay sits on the shore of this small bay on Western Australia's southwest coast, between Cape Leeuwin and Cape Naturaliste.

It is listed among Transport WA's regional boat ramp facilities and provides access for vessels ranging from small to larger boats. The ramp is concrete and free to use, with ample parking and a toilet nearby, though no wash-down facilities are available.

Conditions can be variable — seaweed occasionally affects launching, and swell can make retrieval challenging, with the ramp edges known for drop-offs. Stingrays are a notable presence, frequently congregating near the ramp to feed on scraps left by anglers.
