Cottbus Air Base (German: Flugplatz Cottbus-Nord – "Airport Cottbus-North") (ICAO: ETHT) is a former military airport that is 2 km (1.2 miles) north-west of Cottbus in Brandenburg, Germany.

During World War II the air base in Cottbus was used by the Luftwaffe and during the 1970s and 1980s by the National People's Army.

[1] The airport is currently closed to air traffic, although the concrete runway has been designated for use by cargo flights in the event of an emergency.

There is an aerospace museum on site, the entire runway while still present, is now in use as a solar electric power farm with solar panels mounted on a framework above the runway.

Having been bought by the local government in 2007,[2] the city of Cottbus plans to turn the former air base into an industrial park, creating around 1,000 jobs.
