V Antliae (V Ant) is a Mira variable star in the constellation Antlia. It varies in brightness between magnitudes 8.2 and 14.0 with a period of 303 days.[3] Even at its brightest, it is far too faint to be seen with the naked eye.

V Antliae's variability was discovered by examining Harvard College Observatory photographic plates, and was announced by Henrietta S. Leavitt and Edward C. Pickering in 1913.[5]

1612 MHz OH maser emission was first detected from this star in 1973.[6] The star's water vapor emission line at 22 GHz was first observed at Haystack Observatory in 1973.[7]
