The 2006-07 Rugby Pro D2 is a French rugby union club competition. The season runs alongside the 2006-07 Top 14 competition, which is the highest club competition. At the end of the season, Auch were champions and thus automatically promoted to Top 14. They were eventually followed by Dax who beat La Rochelle in the final providing the second promotion place. Colomiers were relegated to Fédérale 1; Limoges finished in a relegation spot, but were reprieved when Gaillac were denied a professional license for the 2007-08 season due to serious financial problems. The 2006-07 season was also noted for Toulon's signing of top players such as Tana Umaga who played for them for a period during the season.
