Mauricio Alejandro Viana Caamaño (born 14 June 1989) is a Brazilian-born Chilean former footballer who played as a goalkeeper.
Viana was born in São Paulo, Brazil to a Brazilian father and a Chilean mother. When he was 5, he and his mother moved to Limache, where he was raised.[2]
On 4 August 2013, Viana was injured towards the end of a match against Audax Italiano, but played on to the end and saved a late penalty to keep the score goalless. After the match, he received emergency surgery for a perforated intestine.[3]
In 2024, Viana signed with Trasandino in the Segunda División Profesional de Chile.[4] In July of the same year, he announced his retirement due to a serious physical degeneration.[5]
He was a substitute at the friendly matches of the Chile senior team against Paraguay and Peru on December 2011[6] and April 2012[7] respectively. After defeating Peru, Chile won the Copa del Pacífico.[8]
In addition, he represented Chile in a match against Uruguay U23 played in Maldonado, Uruguay. The squad only included under-25 players and was a loss by 6–4.[9]
