Jagdgeschwader 101 (JG 101) was a Luftwaffe fighter-training-wing of World War II.

Formed at Werneuchen from Jagdfliegerschule 1, JG 101 was created in December 1942 and were stationed from 27 January 1943 at Pau, southern France.

An operational training unit, the Geschwader was never officially deployed in combat, although on 5 March 1944 Jagdgruppe West and JG 101 defended Bergerac, Cognac, and other airfields in south west France against a raid by 8th Air Force B-24s.

The unit operated several training types, including the Gotha 143 and Bucker 131 biplanes and the French-built fighter Dewoitine D.520.

The Geschwader was disbanded on 16 April 1945 and 2,400 personnel were transferred to the 10.
