Walvis Ridge (walvis means whale in Dutch and Afrikaans) is an ocean ridge in the southern Atlantic Ocean, extending for thousands of miles, off the coast of southwest Africa. Both it and the Rio Grande Rise originated from hotspot volcanism now occurring at the islands of Tristan da Cunha (the Tristan hotspot), 300 kilometres east of the crest of the Mid-Atlantic Ridge. The eastern section of the ridge is thought to have been created in the Middle Cretaceous period, between 120 and 80 million years ago. The Ewing Seamount is part of the ridge.
