2008–09 Northern Premier League
The 2008–09 was the 41st season for the Northern Premier League Premier Division, and the second season for the Northern Premier League Division One North and South.
As continuing part of non-league restructuring, the Division One South temporarily had 20 teams, while the Division One North contained 21, with a targeted number for both of 22 teams. This naturally affected the number of relegation slots available during the season, as the league attempted to enlarge the size of the divisions at the end of the season.
