Jesús Luis "Koldo" Álvarez de Eulate Güergue (born 4 September 1970) is a former footballer who played as a goalkeeper, currently manager of the Andorra national team.

Due to injury to starter Abel Resino, he was on the bench for the first team in the final of the 1990–91 Copa del Rey, against RCD Mallorca.

In 1994, he joined FC Andorra who competed in the Spanish football league system, going on to remain 14 of the following 15 seasons with the club and retiring aged 39.

[4] On 10 June 2009, Álvarez played his last international, a 6–0 defeat against England for the 2010 FIFA World Cup qualifiers; arguably one of the best players in the match, he received a standing ovation from the opposing fans for his efforts, after he was substituted in injury time.

[9][10] On 25 March 2017, nearly 12 years after the last point won in official matches, Álvarez led the side to a 0–0 draw with Faroe Islands for the 2018 World Cup qualifying campaign.
