Innisfail Aerodrome (Big Bend Airport) (TC LID: CEM4) is located beside Alberta Highway 54, 3.9 nautical miles (7.2 km; 4.5 mi) northwest of Innisfail, Alberta, Canada.

The aerodrome, managed by the Innisfail Flying Club since 1986, offers one asphalt runway (16/34) equipped with night landing lights. The two other runway surfaces (04/22 & 10/28), used during World War II, are in rough condition. There are several hangars at the aerodrome and room for more development. It is host to many activities year-round, including a glider club, the Innisfail Flying Club and a skydiving training facility.

The aerodrome was opened in 1941 as a relief landing field for the Royal Canadian Air Force as part of the British Commonwealth Air Training Plan. Under the direction of General Robert Murray its primary purpose was a training facility for the No. 36 Service Flying Training School (SFTS) located at RCAF Station Penhold.
