Pope Adeodatus I (570 – 8 November 618), also called Deodatus I or Deusdedit, was the bishop of Rome from 19 October 615 to his death.

Adeodatus was born in Rome, the son of a subdeacon named Stephanus or Stephen.

[2] It represents the second wave of opposition to Gregory the Great's papal reforms, the first being the pontificate of Sabinian.

He reversed the practice of his predecessor, Boniface IV, of filling the papal administrative ranks with monks by recalling the clergy to such positions and by ordaining some 14 priests, the first ordinations in Rome since Gregory's pontificate.

[4] One bulla dating from his reign is still preserved, the obverse of which represents the Good Shepherd in the midst of His sheep, with the letters Alpha and Omega underneath, while the reverse bears the inscription: Deusdedit Papæ.
