Evans & Sutherland is a pioneering American computer firm in the computer graphics field. Its current products are used in digital projection environments like planetariums. Its simulation business, which it sold to Rockwell Collins, sold products that were used primarily by the military and large industrial firms for training and simulation.

The company was founded in 1968 by David C. Evans and Ivan Sutherland, professors in the Computer Science Department at the University of Utah.

The two professors were pioneers in computer graphics technology. They formed the company to produce hardware to run the systems being developed in the University, working from an abandoned barracks on the university grounds. The company was later housed in the University of Utah Research Park. Most of the employees were active or former students, and included Jim Clark, who started Silicon Graphics, Ed Catmull, co-founder of Pixar, John Warnock of Adobe, and Scott P. Hunter of Oracle.

In the 1970s they purchased General Electric's flight simulator division and formed a partnership with Rediffusion Simulation, a UK-based flight simulator company, to design and build digital flight simulators. For the next three decades this was E&S's primary market, delivering display systems with enough brightness to light up a simulator cockpit to daytime light levels. These simulators were used for training in in-flight refueling, carrier landing, AWACS, B52 EVS, submarine periscope and space station docking.
