Port Heiden is at the mouth of the Meshik River on the north side of the Alaska Peninsula, in the Lake and Peninsula Borough
. During WWII, Fort Morrow was built here, and 5,000 personnel were stationed at the base.
Today, Port Heiden is a traditional Alutiiq community. The community recently relocated the village inland because storm waves had eroded much of the old townsite and threatened to destroy community buildings. Regular air services are provided.
