Get hyped, Bills Mafia ... the NFL just announced who will be at the center of the training camp edition of "Hard Knocks" -- and the HBO cameras are heading to Buffalo!!

Roger Goodell made the announcement during the league's spring meetings in Minnesota ... saying the reigning AFC East champions will be documented as they prepare for the 2025-26 season.

While the majority of the show will focus on the team's practices ... there's a chance we get a cameo from Hailee Steinfeld -- who, of course, is engaged to the team's star quarterback, Josh Allen.

The two are kinda private with their relationship, so odds are we won't get a full look inside their relationship…
