PT Puppis (PT Pup) is a star in the constellation Puppis. Anamarija Stankov confirmed this star as a Beta Cephei variable.[5] Analysis of its spectrum and allowing for extinction gives a mass 7.94 times that of the Sun, a surface temperature of 19,400 K and luminosity of 6405 Suns.[4]

The star was discovered to be variable by Janet Rountree Lesh and P. R. Wesselius in 1979.[6] It was given its variable star designation in 1981.[7]
