The 2025 Dolphins season was the Dolphins club's third season in the National Rugby League (NRL) competition in Australia. The previous year's assistant coach Kristian Woolf succeeded Wayne Bennett as head coach. Woolf's first victory was in round 5 against the Gold Coast Titans at Cbus Super Stadium.
In round 11 against the New Zealand Warriors at Suncorp Stadium, referee Peter Gough incorrectly called "play on" after New Zealand spilt the ball forward; the next play resulted in a converted try worth six points. At full-time, the Dolphins lost the match by four points. The following week at Accor Stadium, the Dolphins achieved their first ever victory over the Canterbury-Bankstown Bulldogs. Consequently, the Dolphins have recorded wins against every other NRL side since their entry into the competition. In round 14, the Dolphins recorded their largest win by defeating the St George Illawarra Dragons 56-6. This record was overturned by their 58-4 victory against the North Queensland Cowboys in the following round.
Despite finishing the 2025 season in ninth place and missing the finals, the Dolphins scored the most points (721) of any team in the competition. With 278 points, Dolphins winger Jamayne Isaako individually recorded the highest NRL points in 2025.
The following player movements happened across the previous season, off-season, pre-season and mid-season.
The Dolphins finished sixth in the 2025 NRL Pre-season Challenge played in February, prior to the commencement of the regular 2025 NRL season in March.
The league fixtures were released on 21 November 2024.
