Tryall was a British East India Company-owned East Indiaman launched in 1621. She was under the command of John Brooke when she was wrecked on the Tryal Rocks off the north-west coast of Western Australia in 1622. Her crew were the first Englishmen to sight or land on Australia. The wreck is Australia's oldest known shipwreck.
