The United States Semiquincentennial, also called the Bisesquicentennial, the Sestercentennial, or the Quarter Millennium, will be the 250th anniversary of the United States Declaration of Independence. Festivities will mark various events leading up to the Declaration's anniversary on the 250th Independence Day: July 4, 2026.
Official planning for the celebrations began in 2016 with the congressional, non-partisan United States Semiquincentennial Commission. In 2025, President Donald Trump created the White House Task Force on Celebrating America's 250th Birthday to also promote and plan the events. A soft launch of celebrations began with the United States Army 250th Anniversary Parade on June 14, 2025. America250 events formally began on the eve of July 4, 2025.
