2008 Premier League speedway season

The 2008 Premier League was the second division of motorcycle speedway racing in the United Kingdom and the 14th season since its creation in 1995. The league was governed by the Speedway Control Bureau (SCB), in conjunction with the British Speedway Promoters' Association (BSPA).

The League consisted of 16 teams for the 2008 season with the addition of the 2007 Conference League champions the Scunthorpe Scorpions. New rules introduced for 2008 include three points for an away win compared to two points in 2007, and the removal of bonus points, in which a team was awarded an additional point for an aggregate win over a home and away match against another team. The team finishing at the top of the league table at the end of the season after accumulating the most points were declared the Premier League champions. The four highest placed teams were entered into promotion play-offs, whereby the Premier League play-off winner faced the Elite League relegation play-off final losers over two legs. Teams finishing in fifth to twelfth at the time of the fixture cut-off date compete in the Young Shield.

The Edinburgh Monarchs were crowned the Premier League champions after ending the season as the highest placed team. The Somerset Rebels finished second, King's Lynn Stars third and the Rye House Rockets fourth. All four teams took part in the promotion play-off with Edinburgh and King's Lynn reaching the final. Edinburgh won 93–90 on aggregate and faced Elite League team Wolverhampton Wolves, but lost the two-legged promotion/relegation final 106–76.
