The 2014–15 Tampa Bay Lightning season was the 23rd season for the National Hockey League (NHL) franchise that was established on December 16, 1991.

The off-season for the Tampa Bay Lightning began on April 22, 2014, when they were eliminated in a four-game sweep by the Montreal Canadiens. On May 6, 2014, the first off-season transaction involved the Lightning signing their highly touted goaltender Andrei Vasilevskiy to a three-year, entry level contract. Coming into the 2014–15 season, Vasilevskiy is rated as team's top goaltending prospect.

Johnson had 24 goals, 26 assists and a plus-23 rating in 82 games. Johnson led all rookies in total playing time, and was used heavily on the penalty kill. Additionally, Johnson put up five shorthanded goals, which tied for the NHL lead. Johnson was also named to the NHL All-Rookie Team for the 2013–14 season.

On June 9, 2014, the Lightning announced the re-signing of co-Calder Trophy finalist Ondrej Palat to a three-year, $10 million contract extension.
