Polizeiruf 110 is a long-running German language detective television series. The first episode was broadcast 27 June 1971 in the German Democratic Republic, and after the dissolution of Fernsehen der DDR the series was picked up by ARD. It was originally created as a counterpart to the West German series Tatort, and quickly became a public favorite.

The show was meant to compete with those on West German television. To this end it was fairly successful even attracting a following in parts of West Germany which could receive Eastern TV. Its production values were high. Apart from song and dance numbers and appearances from East German celebrities, almost every broadcast featured well-known stars from the west, often after their popularity had peaked in their home countries.
