The 2004 National Lacrosse League season is the 18th season in the NLL that began on December 26, 2003, with the Arizona Sting hosting the Vancouver Ravens. That game was the Sting's first-ever game and the first event held in the new Glendale Arena (now Gila River Arena) in Glendale, Arizona. The season concluded with the championship game on May 7, 2004. Over 19,000 fans, the second largest crowd ever at an NLL game, packed the Pengrowth Saddledome (now Scotiabank Saddledome) to watch the Calgary Roughnecks defeat the Buffalo Bandits 14–11. This game was the first NLL championship game since 1998 that did not feature the Toronto Rock. The collective bargaining agreement (CBA) between the league and the Professional Lacrosse Players' Association expired before the 2004 season, and the lack of a new agreement caused a 12-day players strike in December 2003. On December 17, the NLL and PLPA announced that the previous CBA had been extended by one year, guaranteeing that the 2004 season would be played without strikes or lockouts.

Team movement

2004 was a season of turmoil for the NLL – two franchises disappeared while three others moved cross-country, causing a division realignment. Gone was the three-division format that had been used in the preceding two seasons; the league was now split into East and West divisions. The Ottawa Rebel and New York Saints franchises both folded, and the following teams moved: These three joined Colorado, Calgary, and Vancouver in the West division, while perennial rivals Toronto, Buffalo, Rochester, and Philadelphia were left to fight over three playoff spots in the East.
