The Heilig-Geist-Kirche, Heiliggeistkirche or Heiligengeistkirche was a church in Potsdam dedicated to the Holy Spirit. It was built in 1726-1728 to Baroque designs by Pierre de Gayette and Johann Friedrich Grael with an 86-metre-high tower. It, the Garrison Church and the Nikolaikirche formed the "three church view".
It burned down in the Second World War. The SED leadership had the nave ruins demolished in 1961 and the tower blown up in 1974. Since 1997 the Residenz Heilig Geist Park old people's home has stood on the site, with a tower intended to evoke the former church tower.
