Kilby Provincial Park, Provincial park in Harrison Mills, British Columbia, Canada.

Kilby Provincial Park covers 3 hectares on the east shore of Harrison Bay, where the Harrison River widens before joining the Fraser River, in Harrison Mills. It holds 30 campsites and a boat launch, with a sandy summer beach. The park borders the Kilby General Store, a temperance hotel built on pilings and linked to the railway station by a ramp to its second storey.

Kilby Provincial Park was established on 28 August 1973 and is one of the ten smallest provincial parks in British Columbia. It adjoins the Kilby General Store, a temperance hotel built on pilings that Thomas and Eliza Kilby converted into a general store in 1906. Their son Acton ran it from 1922 until 1977, adding gravity-fed gas pumps in 1926.

The focal building is the 1906 General Store, once a temperance hotel built on pilings and linked to the railway station by a ramp to its second storey. Thomas and Eliza Kilby converted it into a general store that year; their son Acton and his wife Jessie ran it until 1977. Costumed interpreters, farm animals and an orchard playground fill the 3-hectare heritage farm.

The park lies on the eastern shore of Harrison Bay, where the Harrison River widens before joining the Fraser River, in the District of Kent. It adjoins the Kilby General Store site, and the 1906 store and farm buildings stand on an elevated flood plain linked by boardwalks. A boat launch gives river access; the sandy beach is a summer feature.

During salmon spawning season, hundreds of bald eagles gather at the park to feed on the abundant fish. Winter brings migratory trumpeter swans from Alaska that make the river shoreline their temporary home.
