Ha Chonghyun

Ha Chong Hyun (; born 1935) or Ha Chong-hyun is a South Korean artist. Today, through his Conjunction series (1974–present), Ha is best known as a leading practitioner of the Korean monochrome art trend known as Dansaekhwa. After Korea's independence in 1945, Ha returned to Korea.

In 1959, he received his undergraduate degree from the Department of Painting at Hongik University. His teachers at Hongik University included Kim Whanki and Yoo Yongkuk. Two works from 1965 demonstrate Ha's choice to lacerate the canvas, perturbing its paint-covered fibers and exposing their individual threads. Ha participated in the 1965 Paris Biennale with one such work.

Scholars and critics have variously interpreted the arc of these early paintings. Many echo the critic Lee Yil, an early champion of Ha's work, While some art historians argue that Ha attempted to extend his painting beyond two-dimensionality, into the spaces of sculpture and even architecture, Instead, Kim finds Ha's work before and after 1965 to have continuity—in her words, "to reveal as it does characteristically, the material, to accentuate the properties of matter." In the second AG exhibition in 1971, Ha presented Counter-Phase (1971), others have specified that connections to their contemporaneous political context reside on a more latent level. In particular, the art historians Kim Mikyung and Joan Kee have proposed that, respectively, the repressive atmosphere of and ubiquity of military presence during these years inescapably permeated these works.
