The 2017 LNFA season was the 23rd season of American football in Spain.
Teams were divided into three categories, named Serie A, B and C, with promotion and relegation between them.
Badalona Dracs won their eighth title, a record for the tournament.
If two or more teams are tied at the end of the competition, the ranking of teams in each group is based on the following criteria:
Six teams entered the LNFA Serie A, the top-tier level of American football in Spain. Murcia Cobras promoted from the last Serie B while no team was relegated from the previous season.
As an expansion of the league to eight teams was planned, the last qualified team played also the relegation play-offs instead of being directly relegated.
