NGC 2770 is a spiral galaxy in the northern constellation of Lynx, near the northern constellation border with Cancer. It was discovered by German-born astronomer William Herschel on December 7, 1785. J. L. E. Dreyer described it as, "faint, large, much extended 150°, mottled but not resolved, 2 stars to north". NGC 2770 was the target for the first binocular image produced by the Large Binocular Telescope.

The morphological classification of SBc indicates a barred spiral with moderately-wound arms. The physical properties of this galaxy are similar to those of the Milky Way. The combined mass of stars in the galaxy is estimated at 2.1×10 M☉, and it has a star formation rate of ~1.1 M☉ y. There are no apparent perturbations of the galaxy due to suspected interaction with the companion galaxy, NGC 2770B.
