Big Knife Provincial Park, Provincial park at Battle River and Big Knife Creek in County of Paintearth, Canada.

Big Knife Provincial Park is a natural area where Big Knife Creek meets the Battle River in central Alberta. The grounds feature wooded riverbanks, open meadows, and water access spread across several hundred hectares.

Big Knife Creek, which gives the park its name, commemorates a 19th-century fight between Big Man, a Cree, and Knife, a Blackfoot, in which both died. Anthony Henday explored the region in 1754 while searching for bison, and the name appears on his maps. The creek was renamed White Man's Creek in the late 1800s before reverting. The park was established in 1962 and fully opened in 1972.

Big Knife Creek carries the name of a 19th-century fight between Big Man, a Cree, and Knife, a Blackfoot, in which both died. The creek was later renamed White Man's Creek before reverting. Visitors can still find the remains of Jack Nelson's cabin, old gravesites and water stills from early settlement.

The park provides over 40 campsites, with several designated for tents, and typically opens during summer months. Visitors should prepare for changing weather and check seasonal availability before planning their visit.

The area harbors an exceptional variety of butterfly species, including several that are rare and specialized to specific habitats. This insect population makes the park noteworthy for nature observers and collectors.
