Robert Edward Machado (better known simply as Rob Machado) (born October 16, 1973, Sydney, Australia) is an Australian-born American professional surfer from Cardiff-by-the-Sea, a community in Encinitas (San Diego County), California. Machado attended San Dieguito High School, and is known for his casual, "laid-back" style both in and out of the water taught.

Though he rides a modern tri-fin shortboard, he is still considered a "soul-surfer" largely because of his soft-spoken, humble personality and his disinterest in the spotlight, along with his fluid surfing style, which has earned him the nickname "Mr. Smoothy." He is one of the best-known goofy-foot surfers in the world today.
