Kongiganak (Central Yupik: Kangirnaq) is a census-designated place (CDP) in Bethel Census Area, Alaska, United States, and primarily sits on the eastern shore of the Kongiganak River.

The original Kongiganak was settled in the 19th century and was located on a small creek just above Kuskokwim Bay.

The current Kongiganak was permanently settled in the 1960s when former residents of Kwigillingok sought higher ground in search of relief from floods.

The current settlement of Kongiganak first appeared on the 1970 U.S. Census as an unincorporated village.

The racial makeup of the CDP was 2.79% White, 95.82% Native American, and 1.39% from two or more races.

21.5% of all households were made up of individuals, and none had someone living alone who was 65 years of age or older.
