Rocky King Detective (also known as Inside Detective) is an American action/crime drama series that was broadcast live on the DuMont Television Network on Sundays at 9pm ET for most of its run. The series ran for six seasons, from January 7, 1950, to December 26, 1954. From January 7, 1950, to July 22, 1950, the series was broadcast on Saturdays at 8:30pm ET, and from September 8, 1950, to March 9, 1951, it was broadcast on Fridays at 9:30pm ET, until moving to Sundays.

When the series began in 1950 it was seen on nine DuMont stations, and budget limitations forced its star, Roscoe Karns to change in the men’s restroom. In 1953 it was shown on 45 stations and, after moving production to DuMont’s new Tele-Center, Karns obtained his own dressing room. The series became one of DuMont’s most popular shows, lasting nearly to the end of DuMont’s operations.
