John M. Skevin (June 14, 1927 – October 18, 1993) was an American Democratic Party politician who served in both houses of the New Jersey Legislature.
Born in West New York, New Jersey, Skevin attended Memorial High School and graduated from St. John's University and St. John's University School of Law after completing his military service in the United States Army.
He was elected to the New Jersey General Assembly in 1965, but was defeated for re-election two years later by Republicans William Crane and Michael Ferrara.
He ran again in 1969, but lost the Democratic primary to incumbent Lee Carlton and Vincente Tibbs.
A 1983 comeback bid was unsuccessful; he lost the Democratic primary to his former running mate, Assemblyman Paul Contillo.
