HMS St Lawrence was a 14-gun schooner of the Royal Navy. She had been built in 1808 in St. Michaels, Talbot County, Maryland for Thomas Tennant and sold to Philadelphians in 1810. During the War of 1812 she was the US privateer Atlas. The UK captured her in 1813 and renamed her St Lawrence. The US privateer Chasseur recaptured her in 1815, and then HMS Acasta re-recaptured her.
