NGC 777 is an elliptical galaxy in the constellation of Triangulum. It was discovered by William Herschel on September 12, 1784. It has a weak active nucleus of type Seyfert 2 or LINER 2, implying that the central region is obscured. When observed in radio waves the galaxy has a bright nucleus from which emerge small two radio jets about 18 kpc across. The jets are of Fanaroff–Riley class I. It may be an outlying member of galaxy cluster Abell 262.
