The financial terms of the deal were not released, but Pierre LeBrun of ESPN.com reported the value to be $1.55 million.
The 6-foot left wing played 71 regular-season games last season for the St. Louis Blues, finishing the campaign with 13 goals and 12 assists. Morrow ranked eighth on the team for goals and averaged 11:54 in ice time per game.
Morrow was drafted with the 25th overall pick in the 1997 NHL Entry Draft. He spent the first 13 seasons of his NHL career with the Dallas Stars before being traded to the Pittsburgh Penguins in March 2013. The 35-year-old signed with the Blues as a free agent prior to the 2012-13 season.
The Lightning also signed forward Philippe Paradis to a one-year, two-way contract.
