Can I Cleave on / after an Attack of Opportunity

[Quiche Lisp]

If I make a successful AoO, can I use the Cleave feat after that ?

[Craig Mercer]

No, you can not.
Cleave is a standard action, while Attacks of Oppertunity are an interrupt of an action.
In other words, you aren't getting a standard action with an AoO, you are interrupting someone elses action by getting an attack.

Not in pathfinder. 3.5 cleave worked like this, much to the detriment of zombie hordes everywhere.

Cleaving Finish and its Improved kin might interest you.
