The 2017 Baltimore Brigade season was the first season for the franchise in the Arena Football League. The Brigade played at the Royal Farms Arena.

The 2017 Arena Football League season was the 30th season in the history of the Arena Football League (AFL). Prior to the start of the season, the league contracted to five teams. Due to this, for the first time since 1991, the league was not divided into conferences or divisions. The 14-game regular season began on April 7, 2017, when the two new teams, the Baltimore Brigade and the Washington Valor, faced off in the Verizon Center, and ended on August 5, 2017, when the Tampa Bay Storm lost against the Philadelphia Soul.
