Lituya Bay is a fjord located on the coast of the south-east part of the U.S. state of Alaska. It is 14.5 km (9 mi) long and 3.2 km (2 mi) wide at its widest point. The bay was noted in 1786 by Jean-François de Lapérouse, who named it Port des Français. Twenty-one of his men perished in the tidal current in the bay.
