Mamia III Gurieli (Georgian: მამია III გურიელი), also known as Mamia the Great Gurieli (დიდი გურიელი, Didi Gurieli) or the Black Gurieli (შავი გურიელი, Shavi Gurieli) (died 5 January 1714), of the western Georgian House of Gurieli, was Prince of Guria from 1689 to 1714. Involved in civil wars plaguing western Georgia, he became King of Imereti three times in the years of 1701, 1711–1712, and 1713–1714. After his first reign as king for a year in 1701, he abdicated the throne of Imereti, being unable to tolerate the influence of his father-in-law Giorgi Abashidze. Subsequent periods of his royal career was the result of a feud with Giorgi VII of Imereti. Mamia died while still sitting on the throne of Imereti, which then reverted to his rival Giorgi VII.
