HMS Blackwood was a Captain-class frigate of the Evarts-class of destroyer escort, originally commissioned to be built for the U.S. Navy.

Before she was finished in 1942, she was transferred to the Royal Navy under the terms of Lend-Lease, and saw service during the Second World War.

On 25 November Bazely and Blackwood sank U-600 north of Punta Delgada.
