Chester Floyd Carlson (February 8, 1906 – September 19, 1968) was an American physicist, inventor, and patent attorney born in Seattle, Washington.

Carlson invented electrophotography (now xerography, meaning "dry writing"), producing a dry copy in contrast to the wet copies then produced by the Photostat process; it is now used by millions of photocopiers worldwide.
