Mu1 Octantis, Latinized from μ1 Octantis, is a solitary star in the southern circumpolar constellation Octans. It has an apparent magnitude of 5.98, allowing it to be faintly visible to the naked eye under ideal conditions. Located 335 light years away, it is approaching the Sun with a heliocentric radial velocity of {{val|-36|ul=km/s}}.
This object is an F-type star with the blended luminosity class of a giant star and a bright giant. At present it has 1.36 times the mass of the Sun but has expanded to 4.68 times its girth. It radiates at {{val|34.3|ul=solar luminosity}} from its enlarged photosphere at an effective temperature of 6,521 K, giving it a yellow white glow. Mu1 Octantis is metal enriched and has an age of 900 million years.
