The Rockefeller Republicans were members of the United States Republican Party (GOP) in the mid–20th century who held moderate to liberal views on domestic issues, similar to those of Nelson Rockefeller, the governor of New York from 1959 to 1973 and Vice President of the U.S. from 1974 to 1977. Rockefeller Republicans were most common in the Northeast and the industrial Midwestern states (with their larger moderate-to-liberal constituencies), while they were rare in the South and the West.
The term refers to "[a] member of the Republican Party holding views likened to those of Nelson Rockefeller; a moderate or liberal Republican". Geoffrey Kabaservice states that they were part of a separate political ideology, aligning on certain issues and policies with liberals, while on others with conservatives and on many with neither. Luke Phillips has also stated that the Rockefeller Republicans represent the continuation of the Whig tradition of American politics.
