What anniversary of Colorado’s statehood coincides with America250 in 2026?

Colorado’s 150th anniversary of statehood coincides with America250 in 2026.

Colorado was admitted to the Union on August 1, 1876, during the United States’ Centennial year. In 2026, the state reaches 150 years of statehood, while the nation marks 250 years since the Declaration of Independence.

The combined commemoration is branded America 250–Colorado 150. It gives Colorado a way to connect national history with its own political history, including statehood during the period of western expansion after the Civil War.

Colorado’s statehood anniversary is not the same as the anniversary of its settlement, territorial organization, or incorporation as a territory. The 150-year figure specifically counts from admission as a U.S. state in 1876.
