Umkumiute is a small unincorporated community on Nelson Island in the bay, from Toksook Bay. It is located in the Bethel Census Area.
This region was inhabited by the Yupik Eskimos for thousands of years. During the 1950s it was founded as a community. It was later annexed by Toksook bay and is now a neighborhood of Toksook bay Alaska. Long ago Umkumiut is where some people lived for the summer.
The population is estimated at 100.
