Mr. Idol (Korean: Mr. 아이돌; RR: Mr. A-i-dol) is a 2011 South Korean film written and directed by Ra Hee-chan. Ra called it, "a movie that captures young people's dreams through music."

Ji Hyun-woo, Jay Park, Jang Seo-won and Randy Kim play four young men who come from different walks of life to form an idol band, united by their love of music. Though musically talented, they are far from mass-produced pop material, and the movie portrays their rigorous training process under a producer (Park Ye-jin). But a powerful figure in the music industry (Kim Soo-ro) tries to interfere with their rise to superstardom.
