Rigo 23 (born Ricardo Gouveia, 1966) is a Portuguese-born American muralist, painter, and political artist.

He is known in the San Francisco community for having painted a number of large, graphic "sign" murals including: One Tree next to the U.S. Route 101 on-ramp at 10th and Bryant Street, Innercity Home on a large public housing structure, Sky/Ground on a tall abandoned building at 3rd and Mission Street, and Extinct over a Shell gas station.

Rigo create a controversial statue of Peltier that was removed from the grounds of the American University in January 2017.

Their simple gesture of the hand is considered as one of the most controversial statements of political and social activism in Olympic history.

Victory Salute is a monument of that moment which was specifically built on the San Jose State University campus because Smith and Carlos were both student-athletes at the college.
