HMS Bellwort was a Flower-class corvette built for the Royal Navy during World War II.

Bellwort was ordered in July 1939 as part of the Royal Navy's 1939 War Emergency building programme.

After working up and trials she was assigned anti-submarine warfare and convoy escort duties on the West Africa station, based at Freetown.

From March 1942 onwards Bellwort served with close escort groups on South Atlantic convoys, stationed at Freetown.

In three years Bellwort sailed with 42 trade convoys (outbound and homebound), contributing to the safe and timely arrival of more than 800 merchant ships.
