Who are the Hatters?

A Hatter is a student or member of the athletic program at Stetson University in Florida.

Where did the term Hatters come from?

The Hatters get their name from John B. Stetson, the hat maker known for his eponymous Stetson hats. Although the school was founded as DeLand Academy, it was renamed after Stetson joined the Board of Trustees, and the Hatters were born. The name refers to the school’s athletic program and students.

Technically, the school’s mascot is named John B., but the current version, who wears a Stetson hat, green bandana, and alligator skin boots, is also considered a Hatter, like other members of the school family.

How to use the term Hatters

If you’re a student at Stetson or a big fan, it’s almost guaranteed that you’ll use the hashtag “#GoHatters” online and sing the school fight song with the chant “Let’s GO, HATTERS, GO!” You might shout out about your “#StetsonHatters” too.

If you’re not associated with the school, you may associate the term with the “MadHatter of Alice and Wonderland. But, you might want to keep that one under your … well … hat, around the school. They’ve moved on from that version of John B. to his present-day cowboy look.
