LKL Kursis (M51) is a minehunter of the Lithuanian Naval Force. Built in West Germany in 1958 as Marburg (M1080), a Lindau-class (or Type 320) minesweeper for the German Navy, she was upgraded to a Type 331 minehunter in the early 1960s. Germany donated Marburg in 2001 to the Lithuanian Naval Force, which renamed the ship Kursis. The vessel augmented the Squadron of Mine-hunters, which had been established in 1999 with the similar donation of sister ship Koblenz, which became Sūduvis (M52).
