Pierre Gasly has signed a contract extension with Alpine and Lance Stroll has agreed a deal to stay at Aston Martin.
Both drivers will remain until “2025 and beyond”, said their teams, who have not revealed the exact length of the contracts.
Frenchman Gasly, 28, said: “I feel very much at home at this great team.
“I’ve been officially here for over 18 months and it has always been the plan to build a long-term project with the team.”
Canadian Stroll, 25, has been at Aston Martin – owned by his billionaire father Lawrence – since it rebranded from Racing Point in 2021.
“I’m super happy to have committed to staying with the team,” said Stroll, who has scored only 17 points this season.
“It’s amazing to see how far we’ve come in the last five years. We’ve grown so much as a team and there’s still so much more to look forward to.”
Last season Gasly finished third in the Dutch Grand Prix – one of only four podiums for Alpine since they rebranded from Renault in 2021 – and third in the Belgian GP sprint, but he has only five points this season.
“While on track it’s been a challenging season so far, I remain faithful to the project and I am not going anywhere,” Gasly said.
Alpine team principal Bruno Famin said: “He is a driver with huge experience in Formula 1 and continues to show huge amounts of potential on-track.”
This month Alpine said Esteban Ocon will leave at the end of the season.
In April Aston Martin confirmed the re-signing of two-time world champion Fernando Alonso for the next two seasons.
Aston Martin are fifth in the constructors’ championship and Alpine seventh.
The Austrian GP gets under way on Friday.
