The Lemyo River , sometimes spelled Lay Mro, is located in Burma and empties into the Bay of Bengal at Sittwe. It is situated on the side of the ancient Arakanese kingdom, Mrauk-U Township, in Rakhine State. Lay Mro in the Rakhine language means "four cities," which refers to the four ancient Rakhine cities that flourished by the side of the river.
