Luka Sammalisto (born 25 November 2007) is a Finnish racing driver who last competed in the Italian F4 Championship for US Racing.
Sammalisto began karting at the age of seven. During his karting career, he most notably won the 2022 Finnish Karting Championship in OK. Sammalisto also competed in WSK and CIK-FIA competitions during his karting career, in which he was a Kart Republic factory driver from 2021 until 2023.
Stepping up to Formula 4 competition for 2024, Sammalisto joined R-ace GP to compete in the Formula 4 UAE Championship. Taking his first points in race two of the first Dubai round by finishing eighth in race two, Sammalisto took his season-best result at the same venue two weeks later by finishing sixth in race two.
Remaining with the same team for the rest of the year, Sammalisto competed with them in both the Italian F4 and Euro 4 Championships. In the former, Sammalisto scored his first points at Imola by finishing seventh in race three. After not scoring points at Vallelunga and Barcelona and missing two rounds due fractures in three vertebrae, Sammalisto scored two points finishes in the season-ending round at Monza en route to an 18th-place points finish. In Euro 4, Sammalisto raced in the final two rounds of the season, only scoring points in the season-ending round at Monza by finishing eighth in race three.
Sammalisto switched to US Racing for 2025, beginning his season in the Formula Winter Series, where he contested the first and last rounds of the season, taking a best result of fourth in race two at Algarve. Sammalisto then returned to the Italian F4 Championship for the rest of the year, in which he started off the season with a seventh-place finish at Misano. Following a best result of ninth at Vallelunga, he scored his maiden series podium by finishing second in race three at Monza. In the following three rounds, Sammalisto scored a best result of fifth at both Mugello and Barcelona, before ending the year with back-to-back third-place finishes at Misano en route to an eighth-place points finish.
Sammalisto was initially set to step up to the Formula Regional European Championship in 2026 with Trident. However, due to undisclosed reasons, he was replaced by Kai Daryanani for the season.
