Peter Andreas Munch (December 19, 1908 – January 10, 1984) was a Norwegian-born sociologist, educator, and writer. In 1948, he immigrated to the United States as a post-doctoral research fellow studying Norwegian-American rural sociology in the Midwest. He ended his professional career at Southern Illinois University, with a focus on graduate studies and sociological research based on trips to the remote South Atlantic island Tristan da Cunha.
