Teesside International Airport (IATA: MME, ICAO: EGNV), previously Durham Tees Valley Airport, is an international airport located on the River Tees' north side, between Darlington and Stockton-on-Tees, Northern England. It is about 10 mi (16 km) south-west of Middlesbrough. The airport serves the North East and North Yorkshire.

The airport offers connections to seven domestic and five European destinations. The airport has a Civil Aviation Authority (CAA) Public Use Aerodrome Licence (number P518) that allows flights for the public transport of passengers and for flight instruction. Tees Valley Combined Authority owns three-quarters of the airport and Teesside Airport Foundation owns the other quarter.

Originally Royal Air Force (RAF) station Middleton St George, the aerodrome became Tees-Side Airport in 1964, Teesside International Airport in 1987, and Durham Tees Valley Airport in 2004 before reverting to Teesside International Airport in 2019 following a poll indicating 93% of locals preferred the name, with the reversion occurring on 25 July 2019. 'Teesside Airport' was common on local road signs that were either placed before 2004 or on signs with not much space for the then airport name.
