Bill Atkinson (born 1951) is an American computer engineer and photographer. Atkinson worked at Apple Computer from 1978 to 1990.

Atkinson was the principal designer and developer of the graphical user interface (GUI) of the Apple Lisa and, later, one of the first thirty members of the original Apple Macintosh development team,^[1] and was the creator of the ground-breaking MacPaint application, which fulfilled the vision of using the computer as a creative tool. He also designed and implemented QuickDraw, the fundamental toolbox that the Lisa and Macintosh used for graphics. QuickDraw’s performance was essential for the success of the Macintosh GUI. He also was one of the main designers of the Lisa and Macintosh user interfaces. Atkinson also conceived, designed and implemented HyperCard, the first popular hypermedia system. HyperCard put the power of computer programming and database design into the hands of nonprogrammers. In 1994, Atkinson received the EFF Pioneer Award for his contributions.
