The Musgrove Mill State Historic Site is a historic area in Cross Anchor, South Carolina. It was the very site of the Battle of Musgrove Mill, where a skirmish in the American Revolution took place in August 1780.

The Battle of Musgrove Mill erupted when a group of 200 Patriots discovered a Loyalist camp. They initially thought that the Loyalists were of the same number as they are, so they attempted to attack. Sadly, the Loyalists were 300 men more, and the Patriots learned of it too late. A fight ensued and the Loyalists won.

The Musgrove Mill State Historic Site is now a park. It features a visitor center with interpretive exhibits and an outdoor area where folks can enjoy canoeing, picnicking, and fishing.
