Rigo 23 (also known as Rigo <year>, for example, Rigo 95), born (1966) Ricardo Gouveia, is a Portuguese muralist, painter, and political artist residing in San Francisco, California. Although he is known particularly in the San Francisco community for having painted a number of large scale Pop Art inspired "one way" sign murals, such as the "One Tree" mural on the US-101 onramp at 10th and Bryant Streets, the "interstate route" shaped Inner City Home adorning an affordable housing high rise in downtown S.F., or the "Sky/Ground" mural at 3rd and Mission Streets, the bulk of RIGO's work more literally highlights world politics and political prisoners from the Black Panthers of the Angola Three to Mumia Abul Jamal and the American Indian Movement's Leonard Peltier. He is one of the founding members of Clarion Alley Mural Project collective and is still an active member as of 2006 as well as an occasional professor at The San Francisco Art Institute.  He has also designed several installations as part of the 2006 Liverpool Biennial.  He is considered by some art critics and curators to be part of the first generation of the San Francisco Mission School art movement.  
Rigo was born and raised on the Portuguese island of Madeira. He later established himself as an artist in San Francisco, earning a BFA from San Francisco Art Institute in 1991 and an MFA from Stanford University in 1997.  From 1984-2002, Rigo used the last two digits of the current year as part of his name, finally settling upon "23" in 2003.
