The Primera FEB, formerly known as LEB or LEB Oro, is the second basketball division of the Spanish basketball league system after the Liga ACB. It is run by the FEB. The FEB leagues are divided into three categories (the other two are the Segunda FEB and the Tercera FEB). The league was founded in 1996 and is played under FIBA rules.
The league is contested by 18 clubs. Each season, the top-finishing team in the Primera FEB are automatically promoted to the Liga ACB. The teams that finish the season in 2nd to 9th place enter a playoff tournament, with the winner also gaining promotion to the Liga ACB. The three lowest-finishing teams in the Primera FEB are relegated to Segunda FEB.
A total of 81 teams have competed in Primera FEB since its inception in 1996. 19 teams have been crowned champions and 30 teams have gained promotion to Liga ACB, of which only four teams could not play in Liga ACB. Club Melilla Baloncesto is the only team that played all seasons of the league.
