The 2009–10 Tampa Bay Lightning season was the 18th season for the National Hockey League team. Unlike the previous off-season, the Lightning did not make many roster changes. The Lightning improved on their regular season record but failed to qualify for the Stanley Cup playoffs for the third season in a row. The team was sold during the season to Boston-based investor Jeff Vinik. After the season, Vinik fired the Lightning's management team.
Off-season
On May 11, the Lightning gave Rick Tocchet a multi-year contract to make him their full-time head coach, removing the interim tag he held after taking over the position from Barry Melrose, who was fired during the previous season after 16 games. On June 23, NHL CommissionerGary Bettman met with Lightning co-owners Oren Koules and Len Barrie due to philosophical and financial differences over how to build the team. More details were not available to the public because Bettman imposed a "gag-order" over the meetings. By February, the team was sold and both Koules and Barrie were no longer involved. It was also in this time period that Bettman reportedly vetoed a trade between the Lightning and the Montreal Canadiens that would have sent center Vincent Lecavalier to the Canadiens in exchange for goaltender Carey Price, center Tomas Plekanec and an unnamed prospect. With the second overall pick in the Entry Draft, the Lightning selected Victor Hedman from Modo Hockey of the Elitserien. Hedman was considered the top European prospect available. Having acquired a second first-round pick from the Detroit Red Wings, the Lightning used the 29th overall selection on Carter Ashton from the Lethbridge Hurricanes of the Western Hockey League. Among several of the free agent signings the Lightning made included defenseman Mattias Ohlund, goaltender Antero Niittymaki and left winger Alex Tanguay.
Preseason
Regular season
The Lightning ended the regular season having scored the fewest shorthanded goals in the League, with just 2. After the regular season finished with Tampa Bay missing the playoffs, the Lightning fired both General Manager Brian Lawton and Head Coach Rick Tocchet on April 12, 2010.
