A spree killer is someone who embarks on a murderous rampage. This is a slightly ambiguous term, with similarities to mass murderer and serial killer.

The Bureau of Justice Statistics defines a spree killing as "killings at two or more locations with almost no time break between murders." Serial killers are different in that they have cooling off periods between attacks, while mass murderers typically stick to one location.
