T. J. Hooker is an American police drama television program starring William Shatner in the title role as a 15-year veteran police sergeant. The series premiered as a mid-season replacement on March 13, 1982, on ABC and ran on the network until May 4, 1985. The show was then picked up for a further single season by CBS.

The supporting cast includes Adrian Zmed as rookie Officer Vince Romano; April Clough as Officer Vicki Taylor (Season 1 only), replaced by Heather Locklear as rookie Officer Stacy Sheridan (season 2 onwards); and Richard Herd as Captain Dennis Sheridan, portraying officers in the LCPD Academy Precinct of a fictional, unnamed California city; although, according to the statements of its creator, Rick Husky, the acronym L.C.P.D. stands for "Los Angeles County Police Department". Toward the end of the show's second season, James Darren became a regular cast member as Officer Jim Corrigan.
