Lee Seung-hee (Korean: 이승희; born 1970), known professionally as Nikki S. Lee, is a South Korean visual artist with a focus on performance, photography, and film. Lee often explores themes of identity through her work — specifically as it relates to others, rather than individual identity. Her photography series Projects (1997–2001) is her first and most notable work, where she camouflages herself as a member of the social and ethnic groups she poses with. Lee now lives and works in Seoul, South Korea.
