Rune Almenning Jarstein (born 29 September 1984) is a Norwegian professional footballer who plays as a goalkeeper for Herkules.

[citation needed] Jarstein made his debut in the Norwegian top division, aged 18, playing for Odd in 2002.

This gave second-choice goalkeeper Jarstein the chance to show his ability, and he took the keeper spot for the rest of the season.

[14] When manager Pál Dárdai returned to relegation-threatened Hertha in January 2021, Jarstein regained his starting position in goal.

[19] When Jon Knudsen was injured in 2011, Jarstein became the new first-choice goalkeeper at the national team,[20] and was the first choice until the 2014 FIFA World Cup qualification started in September 2012, when Espen Bugge Pettersen played the match against Iceland.
