Gamma Volantis (γ Vol, γ Volantis) is a wide binary star in the constellation Volans. Based upon parallax measurements, it is approximately 142 light years from Earth. It is bright enough to be seen with the naked eye and can be found around 9° to the east-southeast of the Large Magellanic Cloud.

The brighter component, designated γ2 Volantis, is an orange K-type giant star with a stellar classification of K0III and an apparent magnitude of +3.62. Its companion, γ1 Volantis, is an F-type main-sequence star of classification F2V and an apparent magnitude of +5.70. As of 2002, the pair were at an angular separation of 14.1 along a position angle of 296°. Their separation has decreased from 15.7″ in 1826.
