Yes, there absolutely is a derby hat—several things are called that, depending on context.

What a “derby hat” is

  • In classic menswear, “derby hat” is another name for the bowler : a hard felt hat with a rounded crown, created in 1849 by London hat-makers Thomas and William Bowler.
  • In the U.S., “derby” became the common term, while “bowler” is more common in the U.K. and Europe; most modern hatters treat the two names as the same style.

Derby hats and horse racing

  • At events like the Kentucky Derby , “derby hat” often means large, decorative hats (especially women’s hats) with wide brims, bright colors, and embellishments worn as part of race-day fashion.
  • The Kentucky Derby has promoted hats since its early years, modeling dress codes on British race meetings and turning extravagant hats into a central part of the spectacle.

Modern fashion use

  • Many brands now market both traditional bowler-style derby hats and more casual, stylish versions for men and women, treating “derby hat” as a timeless dress accessory.
  • You will also see “derby hats” discussed in online forums and DIY communities, where people make custom or novelty hats specifically for Derby day.
