Coal Aston Airfield also known as Apperknowle Airstrip, is a general aviation airfield located in the village Apperknowle, Derbyshire, 5.8 mi (9.3 km; 5.0 nmi) south of Sheffield.

The unlicensed airfield is just south of a ridge of high ground to the north-east of Dronfield, close to the villages of Summerley, Apperknowle and Coal Aston.

By the late 1920s this had become a civil field which promised, until World War II, to become Sheffield's airport.

The airfield is operated from an on-site farmhouse and prior permission is required for landing.

Its single strip grass runway is 660 m long and not entirely flat, with a dip in the middle and a hump at the eastern end.
