Lee–Jackson Day is a holiday celebrated in the Commonwealth of Virginia in the USA, for the birthdays of Robert E. Lee and Thomas J. "Stonewall" Jackson. The original holiday, created in 1889, celebrated Lee's birthday. Jackson's name was added to the holiday in 1904. In 1983, the holiday was merged with the new federal holiday Martin Luther King, Jr. Day as Lee-Jackson-King Day in Virginia. This merge was reverted in 2000.

Lee–Jackson Day is currently observed on the Friday before Martin Luther King, Jr. Day, which is the third Monday in January. State offices are closed for both holidays^[1].
