Harold Capistran Hollenbeck (born December 29, 1938) is an American lawyer and Republican Party politician who represented New Jersey's 9th congressional district in the United States House of Representatives for three terms from 1977 to 1983.

He served as member of the East Rutherford Borough Council from 1967 to 1969, and in the New Jersey General Assembly from 1968 to 1972.

Hollenbeck was elected as a Republican to the Ninety-fifth Congress, unseating scandal-tainted Democrat Henry Helstoski by a solid margin.

He was an unsuccessful candidate for reelection in 1982 to the Ninety-eighth Congress, a victim of redistricting and negative campaigning by Robert Torricelli, who unseated him by a 54% to 46% margin.
