Liga Nacional de Fútbol Americano (LNFA) is the name of the top gridiron league which operates in Spain.

It was first founded in 1988 and reorganized in 1995 after the merge of several previous Spanish competitions.

The league is run by the Spanish Federation of American Football (Federación Española de Futbol Americano (FEFA) in Spanish language).

At the end of the season, league champion and runner up clinch bids to compete at next year's European Football League, while third and fourth teams classify for the EFAF Cup.

It was created in 2015 with the aim to get more teams in the national leagues.
