asp, popular name for several species of viper, one of which, the European asp ( Vipera aspis ), is native to S Europe. It is also a name for the Egyptian cobra ( Naja haja ). It is believed that the asp that tradition says Cleopatra used to commit suicide was either that cobra or the horned viper ( Cerastes cornutus ) of N Africa.
