The Lillie Parsons was an American two-masted schooner which sank in the Saint Lawrence Seaway near Brockville, Ontario, Canada, in 1877.

On August 5, 1877, she hit a rock, took on water and sank after her cargo shifted during a squall.

[1] The wreck was discovered on August 6, 1963, by three members of the local diving club,[3] complete with 500 tons of coal on board.

She rests at a depth of about 65 feet (20 m), off the shore of Sparrow Island.
