Bay of Belfalas

In J. R. R. Tolkien's fictional universe of Middle-earth, the Bay of Belfalas was a large southern bay in the Great Sea.

The Bay of Belfalas was the remainder of the eastern edge of the Great Gulf that had divided Beleriand from the Lands to the South in the First Age. After the end of the War of Wrath a large section of western Middle-earth was drowned, and with the new coastline the Bay of Belfalas extended from Andrast to the Mouths of Anduin, and then south past Umbar to the unknown southern shores.

Most of the Rivers of Gondor flowed into the Bay of Belfalas, and it had many smaller bays and capes.

The Bay was named for the region of Belfalas (or "Great Shore"), and in it lay the rocky island of Tolfalas.
