Lake Louise (Sasnuu’ Bene’ in Ahtna) is a census-designated place (CDP) in Matanuska-Susitna Borough, Alaska, United States. Although it is an isolated settlement and is close to Glennallen, it is considered part of the Anchorage Metropolitan Area, like all other locations in the Mat-Su Borough. At the 2020 census the population was 15, down from 46 in 2010 and 88 in 2000.
The first recorded name of Lake Louise was Shosubenich, which means "great flat water with many islands". When Lieutenant Joseph Castner first arrived at the lake on August 6th 1898, he named it "Lake Adah" after a pretty girl he knew. However, when Captain Edwin Glenn arrived sometime later, he convinced Castner to change the name to "Lake Louise" in honor of his wife. The U.S. Army established a recreation facility at the lake towards the end of World War II and built the first road into the area. Lake Louise Road runs about 20 miles (32 km) from the Glenn Highway to the lake. There are still several dilapidated cabins at the "Army Point" campground, including one that was used for four days by General Dwight D. Eisenhower before he was president. The lake is home to the Lake Louise State Recreation Area.
