Paul Michiels (born 15 June 1948) is a Belgian singer and songwriter who became popular for his work with the Belgian music group Soulsister. He has earned the nickname Polle Pap, a name he inherited from a childhood job as a milkman in his hometown of Heist-op-den-Berg, where he was born.

Paul started out with a small band called Purple Bus. From 1974 until 1980, he played keyboards for a British-Belgian band called Octopus. After Octopus broke up, Paul then went solo under the name P.P. Michiels. Under that name, he became famous in his home country for a single titled "Females," which notoriously became popular because it was accompanied by a seducing music video.
