Sergei Sviatchenko (born 1952) is a collage artist from Ukraine. He has lived in Denmark since the 1990s. Sviatchenko graduated from Kharkiv School of Architecture in Kharkiv in 1975, and in 1986 he studied a Ph. D. at the National Academy of Visual Arts and Architecture, Kiev.
Sviatchenko works in collage and photomontage. At times he makes use of image material found in books and magazines; in one series of works, Mutatis Mutandis, he cut up and then re-photographed his own photographic negatives. Some of his work has drawn inspiration from the writings of the graphic designer and Constructivist architect Yakov Chernikov, particularly from his 101 Architectural Fantasies, published in 1933.
