Giovanni Angelo Canini (1609–1666) was an Italian painter and engraver of the Baroque period. He is also known as Giovanni Agnolo Canini or Giannangiolo. He was born at Rome, one of three brothers, sons of a stonemason named Vincenzo, all of whom became artists. The elder brother was a painter; while the younger brother, Marcantonio, a sculptor. He was first the pupil of Domenichino as a child, and traveled with him to Naples. There he worked with Antonio Barbalonga. In 1634, at the request of Domenichino, he was commissioned to restore the oil paintings, which had been painted by Passignano on the walls of the chapel of St Sebastian in the Villa Aldobrandini in Frascati.
