Mount Edgecumbe High School (abbreviated MEHS) is a public boarding high school in Sitka, Alaska in the United States. Located on Japonski Island, across Sitka Harbor from the northwestern corner of downtown Sitka, the school is situated on a portion of Sitka's former World War II-era military installations. Established in 1947 after the military abandoned the area, the school was originally operated by the federal Bureau of Indian Affairs (BIA) as part of a network of boarding high schools, which included schools in Eklutna and Wrangell. After several decades of operation by the BIA, the school was briefly closed in the 1980s before being reopened by the Alaska Department of Education, which operates it today.
