Hendrik Johannes Nicasius "Nyck" de Vries (Dutch pronunciation: [ˈnɪɡ də ˈvris]; born 6 February 1995) is a Dutch racing driver, who competes in the FIA World Endurance Championship for Toyota and in Formula E for Mahindra. In formula racing, De Vries competed in Formula One at 11 Grands Prix from 2022 to 2023, and won the 2020–21 Formula E World Championship with Mercedes.

Born and raised in Uitwellingerga, Friesland, De Vries began competitive kart racing aged nine. After a successful karting career—culminating in back-to-back victories at the direct-drive Karting World Championship in 2010 and 2011—de Vries graduated to junior formulae. Signed to the McLaren Young Driver Programme from 2010 to 2019, De Vries won his first championship at the Formula Renault Eurocup in 2014 with Koiranen. He finished third in the 2015 Formula Renault 3.5 Series before winning multiple races in the 2016 GP3 Series. De Vries progressed to FIA Formula 2 for its inaugural 2017 season, winning the title in his third season, driving for ART. De Vries graduated to sportscar racing that year, competing in the LMP2 class of the FIA World Endurance Championship with Nederland. He took his first class win the following season at Fuji, before joining Formula E with the recently established Mercedes team in 2019. In his second season, de Vries took multiple victories as he won his maiden World Championship. Alongside his successes in Formula E, de Vries also became a race-winner in the European Le Mans Series with G-Drive in 2020 and 2021.

A test and reserve driver for Williams, Mercedes, McLaren and Aston Martin, de Vries made his Formula One debut with the former at the 2022 Italian Grand Prix, as a substitute for Alexander Albon. After scoring a points finish on his debut, he joined AlphaTauri for 2023 but was replaced by Daniel Ricciardo after 10 rounds. De Vries moved back to Formula E with Mahindra for his 2023–24 campaign, and signed for Toyota in the Hypercar class of WEC in 2024, winning the 6 Hours of Imola.
