Which strait separates southern Spain from northern Morocco?

The Strait of Gibraltar separates southern Spain from northern Morocco.

This narrow waterway connects the Atlantic Ocean to the Mediterranean Sea. At its narrowest point, the strait is about 14 kilometres wide, and its depth reaches roughly 900 metres in the main channel. The Rock of Gibraltar rises on the European side near the eastern entrance.

The strait has been an important passage for ships, armies and migrating peoples for thousands of years. Ancient Greek and Roman writers associated its entrance with the Pillars of Hercules. Today it remains a major international shipping route linking Europe, Africa and the Mediterranean basin.

Ocean water flows in both directions, with relatively salty Mediterranean water leaving near the surface and denser Atlantic water entering at depth. The strait also has strategic importance because Gibraltar is a British Overseas Territory, while nearby Moroccan and Spanish waters are heavily used for commerce and transport.
