Cristos Gianakos (born January 4, 1934) is an American postminimalist artist known for his large-scale ramp sculptures and installations.

His drawing on Mylar is likewise emphatic ... [and] commands attention because Mr. Gianakos, using acrylic, ink and graphite, has built up a surface so solid that it has a near-metallic sheen.

"[13] Influences such as Russian Constructivism, Suprematism, Minimalism, Constantin Brancusi, Franz Kline and Giorgio di Chirico have been noted in Gianakos' work.

[5] Other notable exhibitions include Artist as Adversary at the Museum of Modern Art in New York (1971),[17] Tit for Tatlin at the Alternative Museum in New York (1984),[18] Walk on, sit down, go through at Socrates Sculpture Park in New York (1987),[19] Large Scale Drawings from the Collection of Wynn Kramarsky at the Aldrich Museum of Contemporary Art (1989) in Ridgefield,[12][20] Pratt Sculpture Park at Pratt Institute in New York (1999),[21] and ron bladen, cris gianakos, max bill, hans josephsohn, beat zoderer, richard long, christoph haerle, richard serra, beatrice rossi, frédéric dedellay und bernhard tagwerker at the Max Bill Foundation in Zumikon, Switzerland (1999).
