John Richard Rarick (January 29, 1924 – September 14, 2009) was a lawyer who served as a Louisiana state district court judge from 1961 to 1966 in St. Francisville, Louisiana, the seat of West Feliciana Parish, and as a Democratic U.S. representative from the Sixth Congressional District from 1967 to 1975. A staunch conservative, he frequently quarreled with his party's increasingly liberal philosophy and leadership.
