Pierre Gasly will remain with AlphaTauri in 2021 after agreeing a new deal.
The 24-year-old Frenchman was dropped by Red Bull last year but he has bounced back impressively, claiming his maiden Formula One win at the Italian Grand Prix in September.
"I'm extremely happy to continue AlphaTauri for another season, " said Gasly, who is ninth in the standings with 63 points.
"This year is going very well, and we are on track to have our most successful season in the team's history.
"I feel we have a very strong relationship, we have managed to take every opportunity that's come our way, the best one at the Italian Grand Prix.
"Winning my first Formula One race in Monza was a very special moment for me, so I'm very proud of that.
"I'll do my maximum to push the team and take all my responsibility to bring it as far forward as I can."
The identity of Gasly's team-mate for 2021 remains unclear with Japanese driver Yuki Tsunoda in contention to replace Daniil Kvyat.
Tsunoda, 20 will test an F1 car – a 2018 AlphaTauri – for the first time in a private test at Imola next week.
