National Indiana Day

The National Indiana Day is observed annually on November 11 (November 16, according to other sources, please contact us if you know for sure), a celebration dedicated to the culture, history and people of the U.S. state of Indiana—the “Hoosier State”.

History of National Indiana Day

The origins of National Indiana Day are informal rather than legislative—it was established to honour Indiana’s heritage, highlights and contribution to the United States. According to sources, the day was created to celebrate Indiana and its residents, commonly known as “Hoosiers”.
While Indiana officially became the 19th state on December 11, 1816, the November 11 date for National Indiana Day appears to have been chosen by popular observance rather than by statute.

Why is National Indiana Day important?

This day offers a chance to recognise and appreciate the diverse contributions of Indiana—from agriculture and industry to culture, sports and education. It brings attention to the state’s identity and its people.
It also encourages both residents and non-residents to explore the many facets of Indiana’s heritage: the landscapes, history, innovations and communities that help define its role within the U.S.

Here are five simple things this day helps emphasise:

• Acknowledging the cultural and historical legacy of Indiana.
• Celebrating the people of Indiana and their “Hoosier” spirit.
• Exploring places and stories unique to Indiana’s development.
