The St. Louis Vipers was a professional roller hockey team based in St. Louis, Missouri as a member of the now-defunct Roller Hockey International.^[1]

The St. Louis Vipers played their first two seasons of home games in the St. Louis Arena, but moved to the newer Kiel Center in 1995. The ownership of the club was led by former NHL St. Louis Blues star Bernie Federko, who also served as the head coach.

On August 16, 1994, the Vipers played the last official sporting event at the St. Louis Arena against the Tampa Bay Tritons in front of 11,146, the second largest Vipers home crowd.

The St. Louis Vipers hosted the 1995 RHI All-Star Game on July 15, 1995 in front of 9,166 at Kiel Center.^[2] The East beat the West with a score of 14-12. Ed Anderson of the East was the game's MVP.

In 1999, the Vipers became Murphy Cup champions. It was the final year of Roller Hockey International's existence.

Over their six-year existence in the 1990s, the St. Louis Vipers had a total home attendance of 332,412 in 71 home games, an average of 4,682 per game (a few hundred less than what was seen as viable, had the league stayed afloat^[3]). The largest home crowd in Vipers history was the final regular season home game in 1997 with an announced attendance of over 14,000 against the New Jersey Rockin' Rollers.^[4]
