2025 Speedway Grand Prix

The 2025 Speedway Grand Prix season was the 31st season of the Speedway Grand Prix era, and decided the 80th FIM Speedway World Championship. It was the fourth series promoted by Discovery Sports Events.

For the first time Great Britain hosted two rounds of the championship. The original schedule showed the National Speedway Stadium in Manchester joining the flagship Principality Stadium in Cardiff on the calendar, but the Cardiff round was subsequently cancelled and replaced with a second grand prix in Manchester. There were eight other rounds, with Poland's allocation reduced from four to three.

Bartosz Zmarzlik was the defending champion having won the title in 2024. He was aiming to equal Tony Rickardsson and Ivan Mauger's record of six world championships.

The choice of the wildcard riders caused significant controversy due to the fact that 2021 Word Champion Artem Laguta and Emil Sayfutdinov were once again omitted, as was 2022 world runner-up Leon Madsen. The 2025 event was also the fourth consecutive year that Zmarzlik was missing some of his strongest rivals.

The title was won by Zmarzlik, who edged out debutant Brady Kurtz by one point to win a sixth world title. Kurtz created history during the season by winning five consecutive Grand Prix, which was a new record. Britain's Dan Bewley completed the podium, while Fredrik Lindgren, Jack Holder, Andžejs Ļebedevs and Robert Lambert all secured their participation in the 2026 series by finishing in the top seven.
