Harrison Wells is the name of several characters portrayed by Tom Cavanagh in The CW's Arrowverse franchise, primarily on the television series The Flash. Wells, created by Geoff Johns, Greg Berlanti, and Andrew Kreisberg, is an original creation for the series and is not based on any existing character appearing in comics published by DC Comics. Most versions of Wells are from parallel universes, defined by their high level of intelligence and scientific knowledge.

The most prominently featured versions of Wells are Earth-1's Harrison Wells (and Eobard Thawne impersonating him); Harry Wells of Earth-2; writer H. R. Wells of Earth-19; detective Sherloque Wells (/ˈʃɜːrloʊk/) of Earth-221; and explorer Nash Wells who temporarily became the series' version of Pariah. Also featured, less prominently, are the Council of Wells and the Council of Harrisons, which consist of various doppelgängers.

Critics and fans have praised Cavanagh's performances as various versions of the character, particularly Harry, although some criticized his performance as H. R. and Sherloque. The Council of Wells and Council of Harrisons received a mixed reception from critics; some praised their humor and Cavanagh's versatility in portraying them while others criticized their skit-like nature.
