2009 Belarusian First League was the 19th season of 2nd level football championship in Belarus. It started in April and ended in November 2008.
The winners of last season (Minsk) were promoted to Belarusian Premier League. Due to reduction of Premier League, the promoted team was replaced by three teams that finished at the bottom of 2008 Belarusian Premier League table (Lokomotiv Minsk, Savit Mogilev and Darida Minsk Raion).
One team that finished at the bottom of 2008 season table (PMC Postavy) relegated to the Second League. They were replaced by the best team of 2008 Second League (DSK Gomel).
Two of the three teams that relegated from Premier League (Savit Mogilev and Darida Minsk Raion) disbanded during the off-season. No teams were invited to replace them, and the planned First League expansion from 14 to 16 clubs did not happen.
Lokomotiv Minsk changed their name to SKVICH Minsk and Dinamo-Belcard Grodno shortened their name to Belcard Grodno prior to the season.
