$λ^1$ Fornacis, Latinized as $Lambda^1$ Fornacis, is a red giant star in the southern constellation of Fornax. It is just visible to the naked eye as a dim, yellow-hued point of light with an apparent visual magnitude of 5.91. The star is located 383 light years from the Sun, based on stellar parallax, and is drifting further away with a radial velocity of +10 km/s.

$λ^1$ Fornacis is a K-type giant star with a stellar classification of K0/1III, showing it has exhausted its core hydrogen and evolved away from the main sequence. It is currently on the horizontal branch, fusing helium in its core. The star has 2.3 times the mass of the Sun and 12 times its radius. It is radiating 66 times the luminosity of the Sun from its photosphere at an effective temperature of 4,770 K. The abundance of elements with mass higher than helium is similar to the Sun.
