Rocky Mountain House and Acton House were a pair of fur trade posts from 1799 to 1876. Rocky Mountain House belonged to the North West Company (NWC) and Acton House to the Hudson's Bay Company (HBC). When the two companies merged in 1821, the name Rocky Mountain House was retained. The posts were opened and closed seven times.
