Keryado was a French fishing trawler that was built in 1904 Silvain for Dutch owners. She was sold to Iceland in 1916 and renamed Thorstein Ingolffson. In 1917 she was acquired by the French Navy for use as the watchboat Chimpanzé. She was sold in 1919 and became the French fishing boat Keryado, later Keryado II. In 1942, she was requisitioned by the Kriegsmarine, serving as the Vorpostenboot V 423 Keryado II. She was returned to her owners in 1945 and was scrapped in 1955.
