Yokohama Marine Tower (横浜マリンタワー, Yokohama Marin Tawā) is a 106 metres (348 feet) high lattice tower with an observation deck at a height of 100 metres in Naka Ward, Yokohama, Japan.

The light characteristic is marked by a flash every twenty seconds, whereby the light's colour is alternating red and green. Originally, at night, the tower shaft itself was lit green and red according to its markings, but now, after the reopening in May 2009, the lights are white.
