Digital Arts may refer to one of the following:
- Digital Arts Inc. (株式会社デジタルアーツ): A Japanese company that makes scan converters and does contract hardware and software development. May have worked on Ultima conversions.   
- Digital Arts, Inc.: A software company in Westlake Village, California, started by Jim Simmons, the programmer behind the first Genesis John Madden Football and NHL Hockey games at Park Place Productions. After those games, Electronic Arts opted to contract Simmons directly (which seemed to spell the end of EA's relationship with Park Place). None of the games Simmons worked on mentions this company, but his LinkedIn profile does, and California records show it was incorporated on July 2, 1991.
