Cirrus fibratus, also called cirrus filosus, ^[2] is a type of cirrus cloud. The name cirrus fibratus is derived from Latin, meaning "fibrous". ^[3] These clouds are similar to cirrus uncinus, commonly known as "mares' tails," yet different in that fibratus clouds do not have tufts or hooks at the end. ^[4] The filaments are usually separate from one another. ^[5]

Like other cirrus clouds, cirrus fibratus occurs at high altitudes. They can indicate an approaching warm front ^[6] and can also be an indication that fair weather will follow. ^[7]
