Pirwa (or Peruwa) is a Hittite deity whose nature is poorly understood. He/she is sometimes referred to as "queen", though archaeologists believe he/she was a male god.
The name may derive from the Hittite peruna or "cliff", and the Pirwa worship seems to have involved horses and horse-related symbols. The deity may also be a reflex of the Proto-Indo-European deity Perkwunos.
