Spirifer is a genus of marine brachiopods belonging to the order Spiriferida and family Spiriferidae. Species belonging to the genus lived from the Middle Ordovician (Sandbian) through to the Middle Triassic (Carnian) with a global distribution. They were stationary epifaunal suspension feeders.

As Spirifer has been described early on, since then, many species have been reassigned.
