"Secret Agent Man" is a song written by P. F. Sloan and Steve Barri. The most famous recording of the song was made by Johnny Rivers for the opening titles of the American broadcast of the British spy series Danger Man, which aired in the U.S. as Secret Agent from 1964 to 1966. Rivers's version peaked at #3 on the Billboard Hot 100 and #4 on the Canadian RPM chart, one of the biggest hits of his career. Numerous covers and adaptations have been recorded since then with the song becoming both a rock standard and one of Johnny Rivers's signature songs.

Philip Gary "Flip" Sloan, known professionally as P. F. Sloan, was an American singer and songwriter. During the mid-1960s, he wrote, performed, and produced many Billboard Top 20 hits for artists such as Barry McGuire, the Searchers, Jan and Dean, Herman's Hermits, Johnny Rivers, the Grass Roots, the Turtles, and the Mamas and the Papas.
