Kwon Sang-woo (born August 5, 1976) is a South Korean actor. He rose to stardom in 2003 with the romantic comedy film My Tutor Friend and the melodrama series Stairway to Heaven.
Kwon Sang-woo, the most visible example of the so-called mom-zzang (slang for "great body") movement, started his career as a fashion model in the late 1990s. His first acting experience was in the TV drama Delicious Proposal, and for the first few years of his entertainment career, he received only minor roles on television, before making his big-screen debut in the martial arts film Volcano High (2001). The following year, he played his first lead role in the comedy Make It Big (2002) together with real-life best friend Song Seung-heon.
Kwon's breakthrough came in 2003 with the phenomenally successful romantic comedy My Tutor Friend, as a troublesome high school boy who is tutored by a college student of the same age (played by actress Kim Ha-neul). This was followed by appearances in My Good Partner, the world's first movie made for mobile phones, and the music video collection Project X.
