The 2025 Prefontaine Classic was the 50th edition of the annual outdoor track and field meeting in Eugene, Oregon, United States. It was held on 5 July May at Hayward Field, it was the 9th leg of the 2025 Diamond League – the highest-level international track and field circuit.

Starting in 2025 a new discipline of events was added called Diamond+, these 4 events per meet awarded athletes with increased prize money whilst keeping the standard points format to qualify for the Diamond league finals. First place earns 8 points, with each step down in place earning one less point than the previous, until no points are awarded in 9th place or lower. In the case of a tie, each tying athlete earns the full amount of points for the place.
