Yukihisa Isobe (磯辺行久, Isobe Yukihisa) (born 1935) is a Japanese artist whose practice has been shaped by his professional interest for ethical ecology. Active and relatively successful as a young painter in the post-war avant-garde, Isobe appeared to abandon his artistic practice when he moved to New York in 1965 and began a career in urban and ecological planning. However, Isobe maintained his passion for the visual arts and began creating two-dimensional works again in the 1990s that now employed a graphic vocabulary of scientific signs and forms. Since its inaugural edition in 2000, Isobe has contributed monumental environmental installations to the Echigo-Tsumari Art Triennale, notably Where has the river gone? in 2000, revealing to spectators man-made changes in the landscape.
