Tim Tramnitz (German pronunciation: [tɪm ˈtʁam.nɪt͡s]; born 16 November 2004) is a German racing driver who last competed in the FIA Formula 3 Championship for MP Motorsport as part of the Red Bull Junior Team.

Tramnitz is the 2021 Italian F4 and ADAC F4 runner-up, and he also finished third in the 2023 Formula Regional European Championship.

Tramnitz started racing in 2011, competing in local karting championships. After winning the regional Hamburg-based series and the Northern German Kart-Challenge in 2013 and 2014 respectively the German moved into national competitions, where he scored his first and only title in the ADAC Kart Academy series in 2017. He became an ADAC Stiftung Sport protégé in late 2017 and remained in karts until 2019.

Having tested a Formula 4 car for the first time in 2019, Tramnitz was announced to be making his single-seater debut in the ADAC Formula 4 Championship in 2020, driving with US Racing. Tramnitz had a solid season, starting the season with a podium during the opening round in Lausitzring. Two rounds later in Hockenheim, Tramnitz returned to the podium in second place. Throughout the season, Tramnitz scored points in all but one race and stood on the podium on six occasions, one capped off with a win in the final race of the campaign at Oschersleben. He finished fourth in the standings with 226 points, beating all but one of his teammates and winning the trophy for the best rookie.

In 2021, Tramnitz returned to ADAC F4 and Italian F4, once again competing with US Racing. He started his ADAC F4 season with a pole and a second place at the Red Bull Ring. After a double third place in Zandvoort, he took his first ADAC F4 win of the season in Hockenheim after a battle with title rival Oliver Bearman. Tramnitz gained form over Bearman during the next two rounds, notching up a double win in the Sachsenring and following it up with a further win in the second Hockenheim round. Sitting 23 points behind Bearman heading into the season finale at the Nürburgring, he was able to win the first race despite a clash with the Briton, but his title chances ended on the opening lap after he was tipped into a spin by Joshua Dufek. Despite that, Tramnitz finished runner-up in the championship with five wins, five poles and nine podiums.

In the Italian series, competing in a partial campaign, Tramnitz started strongly with a double win in Paul Ricard. After a triple podium in Vallelunga, he returned to dominant ways in Austria with another double win. Despite scoring points in the remaining two rounds, he did not score a podium. However, with four wins and nine podiums, he again finished runner-up in the standings.

For 2022, Tramnitz progressed to the Formula Regional European Championship, competing for Trident. Pre-season, Tramnitz's preparations were hampered as he suffered a broken veterbrae during a crash in a Formula 4 test at Estoril. He scored his first points in Imola, with a ninth and seventh place finish. However, a string of retirements contributed to a points drought then only ended during the second race in Budapest, where he secured his best finish of the season with fourth place. Having finished in the points three more times, Tramnitz placed 15th in the standings with 35 points, ahead of teammate Roman Biliński but considerably behind Leonardo Fornaroli.

During the pre-season, Tramnitz competed in the final two rounds of Formula Regional Middle East Championship with R-ace GP. He scored 14 points and finished 20th overall.
