The Battle of Lexington State Historic Site is a state-owned property located in the city of Lexington, Missouri. The site was established in 1958 to preserve the grounds where an American Civil War battle took place in 1861 between Confederate troops led by Major-General Sterling Price and federal troops led by Colonel James A. Mulligan. The site offers a short battlefield loop trail, picnicking, and tours of the battlegrounds and Oliver Anderson mansion.
