Ocean Beach is a tourist attraction located about 5 kilometres (3 mi) South of the town of Denmark in Western Australia.
The beach is part of Ratcliffe Bay and is surrounded to the East by the Nullaki Peninsula and a smaller granite headland, Wilson Head, to the East. Wilson Inlet is contained by a semi-permanent sandbar that forms part of Ocean Beach although a bar channel often exists which moves seasonally along the beach.
The beach is patrolled during the summer months from December to April and a lifeguard is on duty for the Summer Holidays (mid-December to Early February). Swimming between the flags at the base of the Surf Life Saving Club is recommended.
In 1993, four Gray's Beaked Whales or Scamperdown Whales (Mesoplodon grayi) were stranded on the beach, three were eventually returned to sea but the last one died.
