Ruben Kristiansen (born 20 February 1988) is a Norwegian professional footballer who plays as a defender. Kristiansen has played at the highest level in Norway for three clubs, Tromsø, VÃÂ¥lerenga and Brann.
Kristiansen hails from Nordreisa Municipality. He started his career at local club Nordreisa, before moving on to play for Skjervøy, and later Tromsdalen.
In late 2011 Kristiansen signed a three-year contract with Eliteserien club Tromsø.
He signed for VÃÂ¥lerenga in March 2014.
After two seasons at VÃÂ¥lerenga, Kristiansen joined fellow Eliteserien side Brann in 2015, helping them reach promotion at the end of the season.
He subsequently signed several new contracts with the club, stretching all the way through the 2024 season.
In October 2024 Brann announced that Kristiansen would not be offered a contract extension after the season was finished. The following December, his former club Tromsø confirmed that they had signed Kristiansen on a one-year contract.
After only eight appearances in the league, most of them off the bench, it was announced that Kristiansen would not renew his contract with the club, and that he would depart after only one season.
Kristiansen made one appearance for Norway's U23 team in 2012 against Estonia's U23 team, where they lost 2-0.
He made his international senior debut for Norway against South Africa in a friendly game in January 2013.
