The invention discloses a winch two-way overrunning clutch which comprises an outer ring, a first star wheel, a second star wheel, a third star wheel and a plurality of rolling columns. The first star wheel, the second star wheel and the third star wheel are coaxially arranged inside the outer ring. The rolling columns are evenly distributed in the peripheral direction among the outer ring and the three star wheels. A plurality of concave grooves are formed in the peripheral side face of each star wheel to form inner roller paths corresponding to the rolling columns. The three star wheels and the concave grooves matched with the star wheels correspondingly share the same rolling columns. Hexagonal holes are formed in the centers of the first star wheel and the third star wheel. The second star wheel can rotate relative to the first star wheel and the third star wheel by an alpha angle so as to achieve the exceeding or self-locking state. The invention further provides a winch. Due to the adoption of the clutch, the transmission torque is large, the efficiency is high, braking is reliable, no heat is emitted, and the service life is long.
