Ferdinando del Cairo (1666–1748) was an Italian painter of the Baroque period, active in Northern Italy.
He was born in Casale Monferrato, and learned the first rudiments of design from his father, an unknown artist.
He painted history, and, in conjunction with Giacinto Garofalino, was employed to paint the ceiling of the church of Sant' Antonio at Brescia.
He had an elder brother, Giuseppe (or Guglielmo) (1656–1682) who was also a painter.
