Indiana Jones wears a wide‑brimmed brown fedora.

More specifically, it’s a high‑quality felt fedora (often rabbit or beaver fur felt) with a pinched crown, center dent, and a medium‑wide, slightly flexible brim. In the classic films, his hat was originally made by Herbert Johnson of Savile Row in a style known as the “Poet,” which became the template for the iconic Indiana Jones fedora look.
