William Jonathan Richard Stevens (born 28 June 1991) is a British racing driver, who competes in the FIA World Endurance Championship for Jota.

In Formula One, he made his debut at the 2014 Abu Dhabi Grand Prix with Caterham, replacing Marcus Ericsson for the double points race.

He raced in a lot of different championships in Britain and outside, and after finishing 7th in the Rotax class in Super One he joined Formula Renault 2.0.

They had originally planned to run him in first practice session of the 2014 Japanese Grand Prix; however they were unable to return the relevant paperwork to the FIA Contract Recognition Board in time.

[3] The following month he made his Formula One debut with Caterham F1 at the 2014 Abu Dhabi Grand Prix, having previously tested for the team.

[6] In February 2015, Manor Marussia announced Stevens as one of their drivers whilst bringing substantial funding to the team, along with Roberto Merhi.

In the Canadian Grand Prix he qualified behind Merhi but moved up to 17th due to penalties to Jenson Button, Sebastian Vettel and Max Verstappen.

[10] In May 2017 it was confirmed that Stevens would co-drive the JMW Ferrari 488 GTE-Am alongside two Le Mans 'rookies', nineteen-year-old Dries Vanthoor of Holland and British driver Rob Smith.

[11] The team's Ferrari 488 was fresh out of the box, making its race debut, and was quickly on the pace; third-quickest in first free-practice.

[13] In third and final qualifying the team completed race-preparation of the all-new car, and a succession of yellow flags prevented personal improvements for the JMW drivers.

Shortly after 10 pm, the #84 JMW Ferrari took the GTE-Am lead, and from there steadily built up an advantage that extended to over two laps at the finish.

[15] Stevens also in 2017 finished 2nd in the Blancpain GT Series Sprint Cup which included his first GT3 win at Zolder with team-mate Markus Winkelhock.
