Juan de Fuca Provincial Park, Provincial park on the west coast of Vancouver Island, British Columbia, Canada

Juan de Fuca Provincial Park is a 15.28 km² provincial park on the west coast of Vancouver Island, between Sooke and Port Renfrew. It protects shoreline, forest and intertidal habitat along the Strait of Juan de Fuca, and most of the 47 km Juan de Fuca Marine Trail runs through it.

Juan de Fuca Provincial Park was created on April 4, 1996, when British Columbia merged China Beach Provincial Park (1967), Loss Creek Provincial Park (1959) and Botanical Beach Provincial Park (1989). The new park also took in Sombrio Beach and Mystic Beach, which had been unprotected. The Juan de Fuca Marine Trail through the forest along the coast was cut and built in 1995 and 1996.

The park takes its name from Juan de Fuca, the Greek navigator whose reported 1592 voyage for Spain gave the strait its name. The Juan de Fuca Marine Trail was first intended as a section of the Trans Canada Trail and was funded by Parks Canada before being handed to British Columbia; Island Green Forestry built it with 20 labourers and three chainsaw operators.

Access to the park is available from four main starting points: China Beach, Sombrio Beach, Parkinson Creek, and Botanical Beach. Camping facilities are scattered along the coast, and visitors should plan around tidal conditions and weather patterns that change frequently.

Botanical Beach features distinctive tide pools with shale and quartz formations that have attracted researchers since the early 1900s. The site once hosted one of the earliest marine research stations on the Pacific coast, bringing attention to the region's biological richness.
