Ian Cheng (born March 29, 1984) is an American artist known for his live simulations that explore the capacity of living agents to deal with change. His simulations, commonly understood as "virtual ecosystems" are "less about the wonders of new technologies than about the potential for these tools to realize ways of relating to a chaotic existence." His work has been widely exhibited internationally, including MoMA PS1, Serpentine Galleries, Whitney Museum of American Art, Hirshhorn Museum, Fondazione Sandretto Re Rebaudengo, , and other institutions.
