2009 Eliteserien promotion/relegation play-offs

The 2009 Eliteserien promotion/relegation play-offs was the 37th time a spot in the Norwegian top flight was decided by play-off matches between top tier and second level clubs.

At the end of the 2009 season, Bodø/Glimt and Lyn were relegated directly to the 2010 1. divisjon, and was replaced by Haugesund and Hønefoss who were directly promoted.

Background
The play-offs between Eliteserien and 1. divisjon have been held every year since 1972 with exceptions in 1994 and 2011. In 2009, the play-offs took place for the two divisions following the conclusion of the regular season and were contested by the fourteenth-placed club in Eliteserien and the three clubs finishing below the automatic promotion places in 1. divisjon. The fixtures were determined by final league position – two semifinals: 14th in Eliteserien v 5th in 1. divisjon and 4th in 1. divisjon v 5th in 1. divisjon, and the winners then played each other to determine who played in Eliteserien the following season.

Qualified teams
Four teams entered a play-off for the last Eliteserien spot for the 2009 season. These were:
 * Fredrikstad (14th placed team in the Tippeligaen)
 * Kongsvinger (third placed team in the 1. divisjon)
 * Sogndal (fourth placed team in the 1. divisjon)
 * Sarpsborg 08 (fifth placed team in the 1. divisjon)

The four teams first played single game knockout semifinals, and the winners (Kongsvinger and Sarpsborg 08) advanced to a two-legged final for the 16th and last spot in the 2010 Tippeligaen season. Kongsvinger were promoted to the top flight with a 5–4 win on aggregate against Sarpsborg 08.
