A flexible golf putter for use in the game of golf when putting a golf ball into a hole. The construction of the putter serves to limit the amount of bodily movement necessary. By keeping the putter, golfer, and ball in one plane of motion, the precision of the putt is increased and the possibility of error is decreased. The flexible golf putter has a head portion, an elongated shaft portion, a top flexible grip portion mounted on the top end of the shaft portion, and a T-shaped appendage positioned between the shaft top end and bottom end. The appendage provides an additional handle for the putter and is used by the golfer to control movement of the golf ball.
