"The Laughing Policeman" is a music hall song by British artist Charles Penrose (published under the pseudonym Charles Jolly in 1922).

A similar laughing song with the same tune but other subject matter had been in circulation since the 1890s popularized by George W. Johnson of the USA.

In June 1922, Penrose made the first recording of this song, which was released on Regal Records G-7816. The version more usually heard was recorded on 22 April 1926 and released on Columbia Records 4014 and later FB 1184. The composition of the song is officially credited to his wife Mabel under the pseudonym "Billie Grey"; however, the music and melody are taken from The Laughing Song by George W. Johnson which was originally recorded in the 1890s. The Penroses wrote numerous other laughing songs (The Laughing Major, Curate, Steeplechaser, Typist, Lover, etc.), but only "The Laughing Policeman" is remembered today, having sold over a million copies. Its popularity continued into the 1970s, as it was a frequently requested recording on the BBC Radio 1 show Junior Choice. It even had a dance mix made of it, which was released on a 10 inch 45rpm disc, resembling an old-style 78rpm record, with the original version on the other side.

Stikkan Anderson gave the song lyrics in Swedish, as "Den skrattande polisen" ("the laughing police officer"), which was recorded and released in 1955 by Ove Flodin.
