2025 URBA Top 12
The 2025 URBA Top 12 was the 126th. edition of Top 12, a rugby union club competition held in Argentina organised by the Unión de Rugby de Buenos Aires. The tournament was contested by twelve teams, eleven from the Buenos Aires Province and one from the autonomous city of Buenos Aires. It ran from 5 April to 1 November 2025.
Promoted clubs from the 2024 URBA Second division were La Plata and Los Tilos which replaced Champagnat and Atlético del Rosario that had been relegated in the previous season.
Newman won their first league championship after defeating SIC 15–3 in the final. On the other hand, San Luis was relegated to Primera A via playoffs.
Format
The 12 clubs played each other in a double round-robin tournament. As this was the last URBA edition with 12 teams so since 2026 it would be expanded to 14 teams, none of the participants were directly relegated. Instead, the last placed team played a promotion and relegation match to decide which team would remain in the division or would be relegated to the second level.Teams
