NGC 4776 , also listed twice in the catalog as NGC 4759 A , is a 13.0 mag bright lens-shaped galaxy of the Hubble-type S0 in the constellation Virgo and about 122 million light years away from the Milky Way.

Together with NGC 4761 , NGC 4764 and NGC 4778 it forms the "Hickson Compact Group 62" and was discovered on March 25, 1786 by Wilhelm Herschel , who mistakenly thought it, together with NGC 4778, to be an object ( NGC 4759 ). Only John Herschel was able to resolve the two individual objects NGC 4776 and NGC 4778 with an 18-inch reflector telescope during his observation on May 5, 1836 and noted “vF, S, R, vlbM; the preceding of a double nebula ".
