NGC 3311 is a super-giant[2] elliptical galaxy[3] (a type-cD galaxy)[4][3] located about 190 million light-years away[5] in the constellation Hydra.[6] The galaxy was discovered by astronomer John Herschel on March 30, 1835.[7][8] NGC 3311 is the brightest[9][10] member of the Hydra Cluster[11] and forms a pair with NGC 3309 which along with NGC 3311, dominate the central region of the Hydra Cluster.[12]

NGC 3311 is surrounded by a rich and extensive globular cluster system[13] rivaling that of Messier 87 in the Virgo Cluster.[4]
