This nationwide commemoration, led by the U.S. Semiquincentennial Commission and America250.org, invites Americans everywhere to reflect on our shared history, honor the contributions of past and present generations, and unite around the ideals of liberty and resilience that define our nation.

From local block parties and major events like the Great American State Fair on the National Mall to commemorative coins, volunteer service projects, and cultural celebrations across all 50 states, the year-long observance is a once-in-a-lifetime opportunity to celebrate the enduring American story.
