Eagle River is a community within the Municipality of Anchorage situated on the Eagle River, for which it is named, between Joint Base Elmendorf-Richardson (JBER) and Chugach State Park in the Chugach Mountains. Its ZIP code is 99577. Settled by homesteaders, Eagle River has been annexed to the Municipality of Anchorage since the 1970s—a relationship that is, at times, complicated.[1][2][3] On the one hand, Eagle River functions as an Anchorage suburb--many Eagle River residents work, shop, and participate in community life in the Anchorage Bowl. On the other hand, the community is itself a significant business hub between Wasilla and Anchorage, offering shopping, restaurants, recreation and employment.[4] Much of the community is made up of residents from nearby Joint Base Elmendorf-Richardson. Secession efforts have from time to time gained traction by residents who would like Eagle River legally regarded as a separate community. Eagle River also has a close relationship with its neighboring community to the north, Chugiak, with which it shares some history. If Eagle River were not part of the Municipality of Anchorage, it would be classified as one of the five largest cities in Alaska.
