Alexandros George Yamamoto Kattoulas (; born 1 May 2005) is a British racing driver of Japanese and Greek descent competing in the GB3 Championship for Fortec Motorsports.
Kattoulas previously competed for Elite Motorsport in the GB4 Championship.
Career Born in Tokyo in 2005, Kattoulas moved to Singapore in 2011 and began karting in 2014. In his first year of full-time karting in 2015, Kattoulas won the Rok Cup Singapore/Asia title in the Mini Rok class, whilst also finishing runner-up in the Singapore Karting Championship, and debuting on the international stage by racing in the Trofeo Delle Industrie.
The following year, Kattoulas mainly raced in Europe, finishing tenth in the Andrea Margutti Trophy for Babyrace Driver Academy, before switching to EvoKart for the rest of the year and ending the season by finishing fifth in the WSK Final Cup. Stepping up to Junior karting in 2017, Kattoulas finished sixth in the Swedish Karting Championship, and also made a brief appearance in Asia, finishing second in the Rok Cup Singapore standings. Kattoulas stayed in junior karts for 2018 with Forza Racing, but only managed a best overall result of 11th all year, scoring it in the season-opening WSK Champions Cup.
Kattoulas then took a hiatus from racing to finish school, before enrolling in a mathematics course at the University of Nottingham in 2023. Ahead of his second year of studies, Kattoulas opted to prioritize his racing career and subsequently made his single-seater debut in the 2024 GB3 Championship for Fortec Motorsports. Racing in the second-to-last round of the season at Donington Park, Kattoulas took a best result of 17th in race two and concluded the other two races in 20th.
Remaining on the single-seater ladder for 2025, Kattoulas joined Elite Motorsport to race in the GB4 Championship for his first full season in cars. After topping pre-season and pre-event tests at Donington Park, Kattoulas finished third in the first two races of the season at the same venue, before taking sixth in race three to leave Donington third in points. In the following round at Silverstone, Kattoulas took both pole positions before taking his maiden single-seater win in race one and finishing second in race two. Kattoulas then took his fifth podium of the season at Oulton Park by finishing third in race two, before finishing no higher than fourth in the following four rounds en route to a fourth-place points finish.
Kattoulas returned to the GB3 Championship for a full season in 2026 with Fortec Motorsports.
