Lee Seung-taek (born 12 May 1932) is a Korean interdisciplinary artist. He is a sculptor, an installation artist, and a performance artist—conceptualizing in the notion of "anti-concept" or "anti-art" in the Korean art scene.
As one of the first generation pioneers of experimental art in Korea, Lee is known for his "non-sculptural" artworks that include "display of pieces in stone, rope and newsprint." Lee mainly worked independently and created works that deviated from the dominant artistic concepts in Korea. "Unfettered by the demands of crude nationalism or from chasing the so-called international art world," Lee's work came to be seen as "starting point for a different kind of avant-garde lineage." He has strived to investigate new ways of creating art by experimenting with non-material objects.
In 2009, Lee was the first recipient to be awarded Nam June Paik Art Center Prize.
