The fez (, plural fezzes or fezes), as well as its equivalent, the tarboosh ( / , ALA-LC: ṭarbūsh), is a felt hat of two types: either in the shape of a truncated cone made of red felt, or a short cylinder made of kilim fabric, both usually with a tassel attached to the top. The tarboosh and the modern fez, which is similar, owe much of their development and popularity to the Ottoman era.

Fez (French: Fès; ; Berber: Fas, ⴼⴰⵙ) is the second largest city of Morocco, with a population of 1.1 million (2014).
