2023–24 División de Honor Juvenil de Fútbol

The 2023–24 División de Honor Juvenil de Fútbol was the 38th season of the highest-level under-19 football league competition in Spain since its establishment.

Competition format
The format of the competition followed the same pattern as it had since the 1990s. Teams were divided into seven regionalised groups playing each other twice, with the champion of each group and the best runner-up qualifying for the 2024 Copa de Campeones, and four teams in each group relegated to the Liga Nacional.
 * The champion of the Copa de Campeones would get a place in the 2024–25 UEFA Youth League (not transferable if they also qualified due to the club's senior team reaching the UEFA Champions League group stage).
 * The 32 teams with the best record across the 7 groups (i.e. top four in each plus four 5th-placed) after the first round of matches were completed qualified for the Copa del Rey Juvenil, which would be played in the second half of the season.
