Gaspar Bouttats I (Alternative names: Caspar Bouttats, Gasper Bouttats, Gaspard-Martin Bouttats and Jasper Bottats) (Antwerp, c. 1640 - Antwerp, 1695–96) was a Flemish painter and engraver of the Baroque period.
He was born in Antwerp in a family of engravers. He was the son of the engraver Frederick Bouttats I and Marie de Weert. His uncle Philibert Bouttats was an engraver and his younger brother Frederick Bouttats also became a famous engraver. He was trained by his father. He was registered in 1668-69 with the Antwerp Guild of Saint Luke as a "wijnmeester’’ (wine master) which was a title reserved for the children of the members of the Guild and thus indicates that his father was also a member of the Guild at that time. He was dean of the guild in 1690-1.
He was the teacher of his son Pieter Balthazar Bouttats and of Jan Antoon de Pooter, Geeraet van Caseel (1668-9), Michiel van Hove (1672-3), Jan Francis Clouwet (1672-3); Carolus Bouttats (1690-91) and Gaspar de Man (1694-5).
