Antipope Paschal III (or Paschal III) was Antipope from 1164 to 20 September 1168.
His real name was Guido of Crema. Paschal III was the second of the antipopes to challenge the reign of Pope Alexander III. In 1164, a small number of cardinals who had elected Victor IV met again to vote Paschal III as his successor. He was established at Viterbo and successfully prevented the legitimate pontiff from reaching Rome.
