Gamma Pavonis, Latinized from γ Pavonis, is a star in the southern circumpolar constellation of Pavo. With an apparent visual magnitude of 4.22, it is a fourth-magnitude star and thereby visible to the naked eye. From parallax observations with the Hipparcos satellite, the distance to this star has been estimated at Шаблон:Convert. It is drifting closer to the Sun with a radial velocity of −30 km/s.

Compared to the Sun, this star has a 21% greater mass and a 15% larger radius. It is a brighter star with 152% of the Sun's luminosity, which is it radiating from the outer envelope at an effective temperature of 6,112 K. The stellar classification of F9 V puts it in the class of F-type main sequence stars that generate energy through the nuclear fusion of hydrogen at the core. It is a metal-poor star, which means it has a low abundance of elements heavier than helium. Age estimates range from a low of a billion years up to 7.25 billion years. Gamma Pavonis is orbiting through the Milky Way at an unusually high peculiar velocity relative to nearby stars.Шаблон:Citation needed
