1 Lyncis, also known by its variable star designation of UW Lyncis, is a star in the constellation Lynx. It is a red giant of spectral type M3III. It has been classified as a slow irregular variable, after being found to be slightly variable in 1969 by Olin J. Eggen. Its changes in brightness are complex, with two shorter changeable periods of 35–40 and 47–50 days due to the star's pulsations, and a longer period of 1500 days possibly due to the star's rotation or convectively induced oscillatory thermal (COT) mode.
