Ringló (S. "cold fenland") was an important river of the southern regions of Gondor. It rose in the White Mountains above Lamedon, and flowed southwestwards for some 200 miles before it met the sea. Near its mouth was the ancient Elf-haven of Edhellond, and it marked the border between Anfalas to the west and Belfalas to the east. In a later note, Tolkien said the river was first called Ringnen, but its name was changed after the lake that formed at its source at seasons of snowmelting.
