Kacper Woryna (born 31 August 1996) is a Polish Speedway rider.
Born in Rybnik, Woryna began racing in native Poland in the Ekstraliga with his hometown club, Rybnik. After a few years of riding in Poland, Woryna got his first break into British Speedway, riding with the Coventry Bees during the 2016 Elite League season, who beat off competition from his grandfather's former club, the Poole Pirates, to secure his signature. Woryna was recommended to the Bees management by club captain and Speedway Grand Prix rider Chris Harris, and was also given a big thumbs up by another of his new Coventry teammates, former world number 2 Krzysztof Kasprzak.
The following season, he joined Poole and helped the team win the SGB Premiership 2018.
In 2022, he helped Smederna win the Swedish Speedway Team Championship during the 2022 campaign, and two years later, he helped Lejonen win the Elitserien during the 2024 Swedish speedway season.
Woryna comes from a racing family. His late grandfather, Antoni Woryna, rode for the Poole Pirates in the UK and came 3rd in the Speedway World Championship on two occasions, first in 1966 and later in 1970.
