Omega Fornacis, which is Latinized from ω Fornacis, is a wide binary star system in the southern constellation of Fornax. It has a blue-white hue and is faintly visible to the naked eye as a fifth-magnitude star.[ The system lies at a distance of approximately 470 light years from the Sun based on stellar parallax,][ and is drifting further away with a radial velocity of +10 km/s.][

The dual nature of this system was discovered in 1836 by John Herschel. As of 2013, the two components had an angular separation of along a position angle of 246°.[ This corresponds to a projected separation of .][

The magnitude 4.95[ primary, designated component A, is a chemically peculiar][ B-type main-sequence star with a stellar classification of B9V][ It has 3.4][ times the Sun's mass and is radiating around 268][ times the luminosity of the Sun from its photosphere at an effective temperature of 10,910 K.] Component B, the magnitude 7.71[ secondary, is an A-type main-sequence star with a class of A3V.][ It is smaller than the primary, but has a higher projected rotational velocity.][
