Dean Hargrove (born July 27, 1938 in Iola, Kansas) is an American television producer, writer, and director. His background includes graduating the St. John's Military School and attending the UCLA Film School as a graduate student. He specializes in creating mystery series. He frequently works with television producer Fred Silverman and television writer Joel Steiger.
He became a writer for The Man from U.N.C.L.E. late in the show's first season (1964). His biggest involvement with UNCLE was in the second season when he wrote episodes that included a two-parter, "The Alexander the Greater Affair", later repackaged as the film One Spy Too Many. He did not work on the third season of UNCLE and wrote just one two-parter for the short-lived fourth season.
After U.N.C.L.E., he worked at Universal Studios' television section on shows like It Takes a Thief, The Name of the Game and Columbo. He scripted the second Columbo pilot, "Ransom for a Dead Man", and was producer for the second, third and fourth seasons. More recently, he has worked for Viacom Productions and Paramount Network Television, producing the shows Matlock on NBC and ABC from 1986 to 1995, Jake and the Fatman on CBS from 1987 to 1992, and Diagnosis: Murder on CBS from 1993 to 2002.
