Marcel Johannes Marchewicz (born 1 February 1996) is a German racing driver. A homegrown talent of Schnitzelalm Racing from karting to GT3, he is a three-time Nürburgring Langstrecken-Serie champion, most notably in 2023 in SP9 Pro.

Career Marchewicz made his car racing debut in 2019, competing in the KTM X-Bow Battle, after being discovered through the Super Racer programme on RaceRoom. In his only season in the series, Marchewicz clinched the Rookie title, as well finishing second on his ADAC GT4 Germany debut at Sachsenring and making a one-off appearance in the VLN Series for Team AVIA Sorg Rennsport.

Joining Schnitzelalm Racing on a full-time basis for 2020, Marchewicz raced a BMW M240i Racing in the one-make Cup 5 class of the Nürburgring Langstrecken-Serie. Despite not scoring a win throughout the season, Marchewicz's four podiums sealed him the Cup 5 title in his rookie year. Continuing with them for his step-up to GT4 machinery in 2021, Marchewicz won seven of eight starts in SP10 to secure his second NLS class title in as many years. During 2021, Marchewicz also won the 24 Hours of Nürburgring in SP10, as well as taking victory in a one-off DTM Trophy appearance at the Nürburgring with the team's Mercedes-AMG GT4. Towards the end of the year, Marchewicz also made his debut in GT3 machinery, competing for Mercedes-aligned HWA Team at NLS8.

Continuing in GT4 machinery for 2022, Marchewicz remained with Schnitzelalm to contest the majority of the ADAC GT4 Germany season. Competing in four out of six rounds, Marchewicz scored a win and a second place at the Nürburgring en route to a 17th-place points finish. During 2022, Marchewicz also raced with the team on a part-time basis in the Nürburgring Langstrecken-Serie's SP9 class. The following year, Marchewicz continued with Schnitzelalm for a full-season programme in the SP9 class of the NLS. In his first full season in the category, Marchewicz secured the SP9 Pro title with two podiums to his name, as well as winning both qualifier races for the 24 Hours of Nürburgring in Pro-Am. Marchewicz pulled double duty in the team's No. 10 and No. 11 Mercedes-AMG GT3 Evos at the N24, and also entered the Nürburgring and Hockenheimring rounds of the ADAC GT Masters.

During 2023, news emerged of a planned DTM debut for Schnitzelalm Racing in 2024, with team principal Thomas Angerer confirming talks with "various manufacturers" and announcing Marchewicz as first driver. However, the entry was later postponed amid "health reasons" for Angerer, and the plans were never revived.

After a campaign in the 2024 GT4 Winter Series, which yielded four wins and a fourth-place points finish in the Pro standings, Marchewicz continued with Schnitzelalm for a fourth appearance at the 24 Hours of Nürburgring, finishing second in SP9 Pro-Am. During 2024, Marchewicz also made a handful of appearances in ADAC GT Masters with the team, most notably qualifying on pole at the Hockenheimring and finishing second in race one. After racing at the 2025 24 Hours of Nürburgring for Aston Martin-fielding PROsport Racing in SP8T, Marchewicz returned to the event a year later with Reiter Engineering in their KTM X-Bow GTX. During 2026, Marchewicz also reunited with SR Motorsport by Schnitzelalm to race at the Monza round of the GT4 European Series.
