The United States Semiquincentennial is commemorated in 2026.
The anniversary falls 250 years after 1776, the year the Second Continental Congress adopted the Declaration of Independence. The principal national observance centers on July 4, the date traditionally associated with the Declaration and American Independence Day.
The commemoration is distinct from the earlier United States Bicentennial, which took place in 1976. That celebration marked the 200th anniversary of independence and included nationwide events, special coins, stamps, and public ceremonies.
The year 2026 also overlaps with other major American milestones, including the 250th anniversaries of Revolutionary-era events and the FIFA World Cup hosted jointly by the United States, Canada, and Mexico. Those events are separate from the semiquincentennial itself, even when communities combine them in local programming.
