Homathko Estuary Provincial Park, Provincial park at Homathko River estuary in Strathcona Regional District, Canada.

Homathko Estuary Provincial Park is a provincial park in British Columbia, Canada, at the head of Bute Inlet, surrounding the mouth of the Homathko River in the Pacific Ranges of the Coast Mountains. The park lies about 1 metre above sea level, with mountainous terrain to the southeast and hilly ground to the northwest, and the sea close by to the southeast.

British Columbia Parks established this protected area in 1997 to preserve the natural estuarine environment and its ecological functions. The protection decision reflected growing recognition of the region's coastal habitat importance.

The Homathko River and Bute Inlet lie within the traditional territory of the Homalco First Nation, a Coast Salish people whose name is linked to the river and estuary. The park protects the mouth of the river rather than a village site; no settlements stand nearby today.

The park sits at the head of Bute Inlet, about 3,600 km west of Ottawa, and the surrounding area has fewer than two inhabitants per square kilometre, with no settlements nearby. There are no marked trails or facilities, so bring all equipment and supplies. Access is by boat, and tidal and weather conditions shape when a landing at the river mouth is possible.

The park protects the estuary where the Homathko River meets Bute Inlet, a meeting of freshwater and salt water at the head of a deep coastal inlet. The surrounding Pacific Ranges terrain rises steeply from the shore, and the Swedish source notes the area is nearly uninhabited, with no settlements nearby.
