The Piperales are an order of flowering plants. Newer classification systems generally consider them part of the Magnoliid group of Palaeodicotyledons. The order comprises five families.

The Aristolochiaceae are generally included in order Piperales, but some classification systems give them their own order, Aristolochiales. Under the Cronquist system the family Chloranthaceae was also placed here.
