The Rockefeller Republicans were members of the United States Republican Party (GOP) in the 1930s–1970s who held moderate-to-liberal views on domestic issues, similar to those of Nelson Rockefeller, Governor of New York (1959–1973) and Vice President of the U.S. (1974–1977). Rockefeller Republicans were most common in the Northeast and the industrial Midwestern states, while they were rare in the South and the West.
