Lee-Jackson Day is a recognized holiday in the state of Virginia, United States of America. It is observed in honor of the Confederate generals Robert E. Lee and Thomas Jonathan 'Stonewall' Jackson, both native to Virginia. Historically, Lee-Jackson Day was observed on the Friday preceding the third Monday in January, which is Martin Luther King Jr. Day.

The holiday was first established by the Virginia General Assembly in 1889, where it was celebrated on Lee's birthday, January 19. Later, in 1904, it was altered to incorporate both Lee and Jackson and was observed on the last Friday in January annually. However, in 1984, the date of observation was re-adjusted to Martin Luther King Jr. Day.

In 2020, the state of Virginia decided to stop marking Lee-Jackson Day as a state holiday, replacing it with Election Day. This decision was derived from a notion to separate these Confederate icons from mainstream recognition due to their associations with slavery and the Civil War. Despite the state's overall decision, various counties and cities within Virginia still choose to observe the holiday on a local level.
