Lasham Airfield (ICAO: EGHL) is an aerodrome 3.6 miles (5.8 km) north-west of Alton in Hampshire, England, in the village of Lasham.

The airfield was built on farming land in 1942 as a Royal Air Force Station during the Second World War. The RAF ceased operations in 1948, but an aircraft company, General Aircraft Ltd, continued to fly from the airfield. From 1951, the main activity at Lasham airfield became recreational gliding.

The airfield is now the home of the largest British gliding club, also one of the world's largest, Lasham Gliding Society Ltd (LGS), which bought the land in 1999 from the Ministry of Defence. The airfield is also the location of 2Excel Engineering Ltd., a company that maintains jet aircraft for various airlines.

Pilots of powered aircraft visiting the airfield require prior permission and a briefing on its hazards: in particular dense concentrations of thermalling gliders (up to 100 gliders can be in the vicinity at once), winch cables up to 3,000 ft (910 m) above the ground, and occasional movements of large jet airliners. Over-flying aircraft are requested to not fly below 3,618 ft (1,103 m) QNH. The airfield frequency is 131.03 MHz.
