Walvis Bay (English: lit. Whale Bay; Afrikaans: Walvisbaai; German: Walfischbucht or Walfischbai) is a city in Namibia and the name of the bay on which it lies. It is the second largest city in Namibia and the largest coastal city in the country. The city covers a total area of 29 square kilometres (11 sq mi) of land.

The bay is a safe haven for sea vessels because of its natural deepwater harbour, protected by the Pelican Point sand spit, being the only natural harbour of any size along the country's coast.
