The 2025 Netball Super League season was the twentieth season of the Netball Superleague, the elite domestic netball competition in the United Kingdom, held from 14 March to 6 July 2025. Eight teams were involved. 
The 2025 signing window gave all eight clubs the opportunity to make signings and finalise their squads before the season began. The signing window opened on Monday 1 July 2024 and clubs were given until 5pm on Friday 23 August 2024 to register 10 players. This is different than the 2024 season where each team could register 12 players plus 3 training partners. Also new to the 2025 season is the creation of the Under 23 competiton (NXT Gen). Each Super League club also has a Under 23 team in the newly formed Under 23 competition from which they can draw Temporary Replacement Players. Permanent Replacement Players can be drawn from any squad in the league.
