James Henry Clark (born March 23, 1944) is an American entrepreneur and computer scientist. He founded several notable Silicon Valley technology companies, including Silicon Graphics, Inc., Netscape Communications Corporation, myCFO, and Healtheon. His research work in computer graphics led to the development of systems for the fast rendering of three-dimensional computer images.

Clark was born in Plainview, Texas, and endured a difficult childhood. He dropped out of high school after being suspended, and spent four years in the Navy where he was introduced to electronics. Clark began taking night courses at Tulane University's University College where, despite his lack of a high school diploma, he was able to earn enough credits to be admitted to the University of New Orleans. There, Clark earned his Bachelor's and a master's degrees in physics, followed by a PhD in computer science from the University of Utah in 1974.

After completing his PhD, Clark worked at NYIT's Computer Graphics Lab, serving as an assistant professor at the University of California, Santa Cruz, from 1974 to 1978, and then as an associate professor of electrical engineering at Stanford University from 1979 to 1982. Clark's research work concerned geometry pipelines, specialized software or hardware that accelerates the display of three dimensional images. The zenith of his group's advancements was the Geometry Engine, an early hardware accelerator for rendering computer images based on geometric models which he developed in 1979 with his students at Stanford.
