Fiacche is a word in Italian that functions mainly as the feminine plural form of the adjective fiacco or fiacca, meaning sluggish, languid, or lacking energy. The corresponding masculine forms are fiacco (singular) and fiacchi (plural), while the feminine singular is fiacca.

Etymology traces the root fiacc- to a sense of weakness or lack of vitality, though precise historical development is not always detailed in simple lexicons. In standard Italian, there are no widely recognized meanings of fiacche beyond its role as the feminine plural of a descriptive adjective, with possible regional variations in usage.
