"Back Door Man" is a blues song written by Willie Dixon for Howlin' Wolf, released by Chess Records as a B-side to Wolf's "Wang Dang Doodle" in 1961 (catalog no. 1777). The song is considered a classic of Chicago blues.
In southern culture, the phrase "back-door man" refers to a man having an affair with a married woman, using the back door as an exit before the husband comes home. "When everybody trying to sleep, I'm somewhere making my midnight creep. / Every morning the rooster crow, something tell me I got to go / I am a back door man", Wolf sings. The promiscuous "back-door man" is a standard theme found in many blues, including those by Charley Patton, Lightnin' Hopkins, Blind Willie McTell and Sara Martin: "every sensible woman got a back-door man," Martin wrote in "Strange Loving Blues" (1925). Robert Plant references the Dixon song in Led Zeppelin's "Whole Lotta Love" (1969): "Shake for me girl, I want to be your back-door man." The phrase "back-door man" dates from the 1920s, but the term became a double entendre in the 1960s, also meaning "man who practices anal intercourse."
