Giovanni Battista Innocenzo Colombo (16 December 1717 – 10 April 1801) was a Swiss painter and stage set designer. Born in Arogno, he was a pupil of his uncle, Luca Antonio Colomba. He worked in Frankfurt, Mannheim, Vienna, Hamburg, Prague, Munich and other cities. For 18 years, he was the court architect at Stuttgart and stage set designer for the Duke. He also worked in Turin, but his major work was a large ceiling fresco at the Ludwigsburg Palace.
