Classification
APG system
In the APG II system, of 2003, this order is placed in the clade magnoliids and is circumscribed as follows:
order Piperales

This is an expansion from the APG system, of 1998, which used the same placement (in the magnoliids) but used this circumscription:
- order Piperales
- family Aristolochiaceae
- family Lactoridaceae
- family Piperaceae
- family Saururaceae
Lactoridaceae is now no longer maintained; its sole genus Lactoris is placed in Aristolochiaceae.
Earlier systems
The Cronquist system, of 1981, placed the order in the subclass Magnoliidae of class Magnoliopsida [=dicotyledons] and used this circumscription:
- order Piperales
- family Chloranthaceae
- family Piperaceae
- family Saururaceae
The Engler system, in its update of 1964, placed the order in subclassis Archychlamydeae in class Dicotyledoneae [=dicotyledons] and used this circumscription:
- order Piperales
- family Chloranthaceae
- family Lactoridaceae
- family Piperaceae
- family Saururaceae
The Wettstein system, latest version published in 1935, assigned the order to the Monochlamideae in subclass Choripetalae of class Dicotyledones. It used the circumscription:
- order Piperales
- family Piperaceae
