HD 160342 is a star in the southern constellation of Ara. HD 160342 is its Henry Draper Catalogue designation. It has an apparent visual magnitude of 6.35[10] and, based upon parallax measurements, is approximately 960 light-years (293 parsecs) distant from Earth.

With a stellar classification of M3 III.[4], this is an evolved red giant that is on the asymptotic giant branch.[10] It is a variable star that is classified as irregular,[3] although changes in brightness of 0.1127 magnitudes at the rate of 0.37943 cycles per day (once every 2.6 days) have been detected in Hipparcos photometry.[11] It has been given the variable star designation V626 Arae (V626 Ara).
