Cypress Hills Interprovincial Park is a provincial park in Canada straddling the Alberta-Saskatchewan boundary. It is jointly administered by the two provinces.
Cypress Hills Interprovincial Park consists of three areas - the Centre Block and West Block in Saskatchewan, and the Alberta Block. Centre Block is a protected area which has fully developed year-round tourist facilities and is 30 km south of Maple Creek on Highway 21. The West Block wilderness area offers rustic camping and provides access to Fort Walsh National Historic Site adjacent to the park boundary. The West Block is 45 km southwest of Maple Creek on Highway 271. The Alberta Block contains the tourist destination of Elkwater, a community with campground facilities on the southern shore of Elkwater Lake; the townsite is mainly made up of summer cabins. Elkwater is about 70 km southeast of Medicine Hat on Highway 41. The West Block and Alberta Block are contiguous with a combined of protected area.
There is also an east block of the Cypress Hills, near Eastend, Saskatchewan; however, it is not a park or protected area.
The Cypress Hills plateau rises up to above the surrounding prairie, to a maximum elevation of at "Head of the Mountain" at the west end in Alberta, making it Canada's highest point between the Canadian Rockies and the Labrador peninsula. Eastward across the boundary is the highest point in Saskatchewan, at . The "West Block" of the Cypress Hills spans the provincial boundary. Battle Creek runs through the central part of the park. Although the hills seem relatively low, in a larger geographic context the plateau does rise gradually from many kilometres away so that the total elevation gain from Medicine Hat is approximately .
The park protects the majority of the Cypress Hills landscape, which consists of three separate elevated blocks of lush forest and fescue grassland surrounded by dry mixed-grass prairie. Approximately 700 species of plants and animals thrive in the park, including 14 species of orchids.
The hills, because of the higher precipitation they receive, support extensive forest and also some rare fescue grassland. Most of the flora is shared with the mountains in states such as Montana and Wyoming rather than with the rest of Canada. The altitude of the hills, which is similar to the altitude of Banff also shares some similar flora and fauna with the Alberta mountain parks. Southern facing slopes tend to support prairie, northern slopes are covered with forest.
The hills host cougars. Cattle graze throughout the Cypress Hills Provincial Park, especially on the prairie on the flat tops of the Hills, though stream bank damage in the spruce/lodgepole pine/aspen forest indicates their presence everywhere in the Hills. There are 5 species of large hoofed mammals found in the park: Wapiti, Mule Deer, White-tailed Deer, Pronghorn, and Bison.
The climate of the area is generally temperate. Because the Cypress Hills area of the same elevation as the Banff townsite, it receives more precipitation than the surrounding areas.
Cypress Hills Interprovincial Park is easily accessible from the Trans-Canada Highway, which passes north of the area. The Centre and West Blocks can be accessed from Saskatchewan Highway 21 south for to Maple Creek, where travellers can either continue 30 km south on Highway 21 to Center Block or southwest for 45 km on Highway 271 to West Block. The Alberta Block can be accessed from the Trans-Canada Highway by following Alberta Highway 41 south near the community of Irvine (33 km east of Medicine Hat) south for 34 km. The nearest airport is located in Medicine Hat.
There are no fees required for entry into the park, but there are fees for camping.
The blocks offer road access within their respective blocks; however, road travel between the blocks is limited. There are gravel roads which connect the blocks, but it is recommend to inquire locally before travelling, especially during the winter. Alberta Highway 515/Saskatchewan Grid 274 connect Maple Creek with Alberta Highway 41, but it is also a gravel road. Travellers desiring to travel all-pavement between the blocks will have to utilise the Trans-Canada Highway.
Cypress Hills Interprovincial Park is a wilderness area with limited cell coverage. The nearest hospital is located in Medicine Hat.

Do not approach, harass or attempt to feed wildlife or livestock. Moose, deer and other wildlife may appear docile. However, wildlife can be quite dangerous to humans and pets if they feel threatened. A pet's actions can provoke an attack. Always keep pets on a short leash. Cougars were historically found in the Cypress Hills. Today, occasional sightings of cougars are reported in the region, including in the park. Parks Division staff work to protect this species while minimizing risk to campers and area residents. Leave the area immediately if you see a cougar or evidence of cougar activity. The chance of seeing a cougar in the Cypress Hills is small.
