2023–24 Campeonato Nacional de Rugby Divisão de Honra

The 2023–24 Campeonato Nacional Divisão de Honra competition, also known as TOP 10, is the 65th Portuguese domestic rugby union club competition operated by the Federação Portuguesa de Rugby (FPR).

Format
The top six teams at the end of the regular season (after all the teams played one another twice, once at home, once away) enter a knockout stage to decide who will be crowned Portuguese champions. This consists of three rounds: the teams finishing third to sixth in the table play quarter-finals (hosted by the third and fourth placed teams). The winners then face the top two teams in the semi-finals, with the winners meeting in the final at the Campo de Rugby do Jamor in Oeiras.

Points are awarded according to the following:
 * 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, while scoring at least 3 more tries than the opponent.
 * 1 bonus point is awarded to a team that loses a match by 7 points or fewer

Promotion and relegation
The bottom team in the relegation play-out is relegated to the Campeonato Nacional de Rugby I Divisão, while the team that finishes 1st in the second tier of rugby union competitions in Portugal will replace the latter.

Following the refusal of the lower division champion RC Montemor of competing in this division, the same 10 teams that played last season will remain and compete again in the TOP 10. João Reis, the president of RC Montemor, stated, "We declined the promotion. We do not have the human or financial resources to maintain a level of competitiveness in that higher division."

For the first time in Portuguese rugby history, the final will be broadcast on free to air television channel Televisão Independente, as a result of a greater interest in rugby following Portugal's participation in the 2023 Rugby World Cup.

An inquiry was opened as a consequence of the incident with fans on 27 April Direito's match, resulting on the provisional ban of Direito's home ground by at least 8 matches.
