2023–24 División de Honor de Rugby

The 2023–24 División de Honor is the 57th season of the División de Honor, the top flight of Spanish domestic rugby union.

Valladolid won its seventh title in eight years, its thirteenth overall, defeating local rivals El Salvador in the final.

Competition format
The season took place between October and May.

Points were awarded as follows:
 * 4 points for a win
 * 2 points for a draw
 * 1 bonus point is awarded to a team scoring 4 tries or more in a match
 * 1 bonus point is awarded to a team that loses a match by 7 points or fewer

Each team played twelve games - one game against each opponent. Then the league divided into two groups: the top six teams progressed to Group A and the remaining six teams progressed to Group B. The teams played the other members of their groups once more.

Eight teams progressed through to the playoffs, meaning the top two teams from Group B qualified along with the six teams from Group A.

Promotion and relegation
The second-tier División de Honor B is made up of three regional groups. The top eight teams across the three groups play off; the champion is promoted to División de Honor, at the expense of the team which finishes last in the División de Honor.

The runner-up plays a further playoff against the team which finishes 11th in the top flight.

Gernika RT and La Vila were relegated while Alcobendas were promoted.
