Patrick Jerome Hillings (February 19, 1923 – July 20, 1994) was a Republican U.S. Representative from California who succeeded Richard M. Nixon in Congress.

He attended the University of Southern California until March 1943, when he entered the United States Army Signal Corps.

He served as a delegate to the Republican National Conventions in 1952, 1956, 1960, and 1964 and supported Dwight D. Eisenhower (twice), Nixon, and Barry Goldwater, respectively.

After four terms in the House of Representatives, Hillings did not seek renomination in 1958, but was an unsuccessful candidate for Attorney General of California, an office vacated by Edmund G. "Pat" Brown Sr. in his successful bid for governor.

Hillings was defeated by Democrat Stanley Mosk, who would later become the longest-serving justice in the history of the California Supreme Court.
