Kennersley Castle (or Kinnersley Castle), was a merchantman launched in 1811. She made several voyages transporting British troops. She also twice transported emigrants from Britain, once to South Africa and then once, most notably because of the subsequent notoriety of her destination, to the at best misguided and at worst fraudulent colony of Poyais. She was wrecked in 1833 and her remains were burned in 1834.
