The Forstbotanischer Garten Köln is an arboretum and woodland botanical garden located at Schillingsrotterstraße 100, Rodenkirchen, Cologne, North Rhine-Westphalia, Germany. It forms part of the city's outer green belt and is open daily without charge.
The garden was created between 1962–1964 on a former military site which was, until the end of World War I, a part of the Äußerer Festungsring Köln, the outer ring of fortresses surrounding Cologne. Its ruins have been integrated into the plantings as a rock garden. In the 1980s, an adjoining natural area was created as the Friedenswald with additional tree plantings.
