Daniel Ricciardo will leave RB with Liam Lawson replacing him for the remainder of the Formula One season.
Speculation surrounding Ricciardo's future has been confirmed as the Australian's second F1 stint was brought to an end after he lost his seat at RB.
Ricciardo is 14th in the drivers' championship standings, while he recorded the fastest lap during last weekend's Singapore Grand Prix - the 258th and final race of his F1 career.
The 35-year-old has chalked up eight wins and 32 podiums along the way, notably finishing third in the drivers' championship in 2014 and 2016.
Lawson, who deputised for the injured Ricciardo in five races last season, will step up from his reserve role to partner Yuki Tsunoda for the final six races of the 2024 campaign, starting at next month's United States Grand Prix in Austin.
The 22-year-old recorded an impressive ninth-place finish in Singapore during his short stint, and RB boss Laurent Mekies feels it will be "a natural transition" for him.
"Everyone would like to thank Daniel for his hard work across the last two seasons with us," Mekies said.
"He has brought a lot of experience and talent to the team with a fantastic attitude, which has helped everyone to develop and foster a tight team spirit.
"Daniel has been a true gentleman both on and off the track, and never without that smile. He will be missed, but will always hold a special place within the Red Bull family.
"I'd also like to take this opportunity to welcome Liam. He already knows the team well. He drove for us last season, and coped well under difficult circumstances, so it'll be a natural transition.
"It's great to see young talent from within the Red Bull family make the next step. We're looking forward to getting our heads down and focusing on the rest of the season together."
