Robert W. 'Bo' Welch III is an American production designer, art director, film and television director, and occasional actor. He is best known for his collaborations with directors such as Tim Burton and Barry Sonnenfeld.

Born in Yardley, Pennsylvania, Welch worked as a production designer on three consecutive Tim Burton films (Beetlejuice, Edward Scissorhands, and Batman Returns), as well as on the Barry Sonnenfeld films Men in Black and Wild Wild West, among other films. He made his directorial debut with The Cat in the Hat, based on the beloved Dr. Seuss book of the same name, which was a critical and commercial disappointment.
