HMS Loch Fada was the lead ship of the Loch-class frigates of the British Royal Navy, built by John Brown & Company of Clydebank, Scotland, and named after Loch Fada in the Inner Hebrides.

The Loch class was a class of anti-submarine (A/S) frigate built for the Royal Navy and her Allies during World War II. They were an innovative design based on the experience of three years of fighting in the Battle of the Atlantic and attendant technological advances. Some shipyards had trouble building these larger ships, which led to widespread use of the Castle-class corvette, introduced around the same time.
