Gliese 832 (Gl 832 or GJ 832) is a red dwarf star (spectrum M1.5V) in the constellation Indus. It is located relatively near our Sun, at a distance of 16.1 light years.

In September 2008, it was announced that a Jupiter-like planet had been detected in a long-period, near-circular orbit around this star (false alarm probability thus far: a negligible 0.05%). It would induce an astrometric perturbation on its star of at least 0.95 milliarcseconds and is thus a good candidate for being detected by astrometric observations. Among currently-known exoplanets, it would have an angular distance from its star second only to Epsilon Eridani b, although direct imaging is problematic due to the star/planet contrast.
