The Russian monitor Admiral Greig was the second and last of the two Admiral Lazarev-class monitors built for the Imperial Russian Navy in the late 1860s. She was assigned to the Baltic Fleet upon completion and remained there for her entire career. Aside from one accidental collision, the ship's service was uneventful. She was reclassified as coast-defense ironclad in 1892 before she became a training ship later that decade. Admiral Greig was stricken from the Navy List in 1909 and scrapped in 1912.
