Gyalpo spirits are one of the eight classes of haughty gods and spirits (Wylie: lha srin sde brgyad) in Tibetan mythology and religion. Gyalpo (Tibetan: རྒྱལ་པོ་, Wylie: rgyal po), a word which simply means "king" in the Tibetic languages, in Tibetan mythology is used to refer to the Four Heavenly Kings (Tibetan: རྒྱལ་ཆེན་བཞི་) and especially to a class of spirits, both Buddhist and Bon, who may be either malevolent spirits or oath-bound as dharmapalas (Wylie: chos skyong, bon skyong).
