The 2023 Prefontaine Classic was the 48th edition of the annual outdoor track and field meeting in Eugene, Oregon, United States.

[2] Grant Fisher broke his own American record in the 3,000 Meters, finishing in 3rd place with a time of 7:25:47.

On the final day, Ingebrigtsen won his second 2023 Diamond League title in the 3000 metres while running the third-fastest time in history.

[3] Second-place finisher Yomif Kejelcha, who was beat by just 0.01 seconds, was upset with the Diamond League hosting the finals over 3000 m instead of the standard 5000 metres distance, saying that benefitted Ingebrigtsen.

Regardless of points accumulated throughout the season, winners of the 2023 Prefontaine Classic were crowned 2023 Diamond League champions in their respective events, with the exception of Athing Mu who was a National Wildcard and thus ineligible for the Diamond League trophy.
