Günther C. Kirchberger (22 August 1928; Kornwestheim – 5 April 2010; Göppingen) was a German painter and professor.
Kirchberger studied at the State Academy of Fine Arts Stuttgart from 1950-1954 where he came in close contact with abstract painter Willi Baumeister.
In 1956 he went to London and became friends with Lawrence Alloway, Denis Bowen and Ralph Rumney.
In 1960 he comes in contact with the philosopher Max Bense and his circle, and 1964 he finally becomes a pure Hard Edge painter.
Since 1964 he taught at the Werkkunstschule (School of Applied Arts) in Krefeld and began working with so called do-it-yourself paintings.
