Do you men besides Valinor and Númenor? Not before the Change of the World if we accept the notion that Arda was flat before then. Afterwards, when Arda became a sphere, Valinor was removed from the world and Númenor sank beneath the sea? Yes! In his essay "Akallabêth" ("The Downfall of Númenor") Tolkien wrote:
For Ilúvatar cast back the Great Seas west of Middle-earth, and the Empty Lands east of it, and new lands and new seas were made; and the world was diminished, for Valinor and Eressëa were taken from it into the realm of hidden things.
And all the coasts and seaward regions of the western world suffered great change and ruin in that time; for the seas invaded the lands, and shores foundered, and ancient isles were drowned, and new isles were uplifted; and hills crumbled and rivers were turned into strange courses.
One of those Empty Lands (Dark Land, also called South Land) probably broke up into what would become Antarctica, Australia and Indonesia. The new lands would have included what we know as the Americas.
