The First Battle of Lexington, also known as the Battle of the Hemp Bales or the Siege of Lexington, was an engagement of the American Civil War, occurring from September 12 to September 20, 1861, between the Union Army and the pro-Confederate Missouri State Guard, in Lexington, the county seat of Lafayette County, Missouri. The State Guard's victory in this battle bolstered the already-considerable Southern sentiment in the area, and briefly consolidated Missouri State Guard control of the Missouri River Valley in western Missouri.

This engagement should not be confused with the Second Battle of Lexington, which was fought on October 19, 1864, and also resulted in a Southern victory.

Prior to the Civil War, Lexington was an agricultural town of over 4,000 residents and county seat of Lafayette County, occupying a position of considerable local importance on the Missouri River in west-central Missouri. Hemp (used for rope production), tobacco, coal and cattle all contributed to the town's wealth, as did the river trade. Many residents were slaveowners, like those of adjacent counties; slaves comprised 31.7% of the Lafayette County population.

Following the battle at Boonville in June 1861, Brig. Gen. Nathaniel Lyon ordered the 5th Regiment of the United States Reserve Corps to occupy Lexington. The regiment was composed primarily of Germans from St. Louis and it had participated in the Camp Jackson Affair. Arriving on the steamer White Cloud on July 9, they were commanded by Colonel Charles G. Stifel. Stifel's second in command was Lt. Col. Robert White, who was often the primary point of contact with the local civilians. Stifel selected the defunct Masonic College as his headquarters and the soldiers began entrenching and fortifying the position.
