The 1999 National Lacrosse League season is the 13th season in the NLL that began on December 26, 1998, and concluded with the championship game on April 23, 1999. The Toronto Rock celebrated their first season in Toronto by winning the championship, defeating the Rochester Knighthawks 13–10 at Maple Leaf Gardens.
The playoffs featured the lowest score by a team in NLL history, when goaltender Bob Watson and the Toronto Rock defeated the Philadelphia Wings 13–2.
The only change of teams from the 1998 NLL season to 1999 was the movement of the Ontario Raiders from Hamilton down the QEW to Toronto to become the Toronto Rock.
