The Brazilian, whose older brother Pietro Fittipaldi is reserve driver for the Haas Formula 1 team, announced the news on social media on Saturday.
Fittipaldi has been in talks with Red Bull motorsport adviser Helmut Marko for some time, after meeting the Austrian at the Dutch Grand Prix in September.
Fittipaldi made his F2 debut in 2021 with Charouz, where he led three race weekends for the team before signing up for a full program this year.
He scored three second places in the feature races at Imola, the Red Bull Ring and the Hungaroring respectively, as well as three third places. He is sixth in the championship standings ahead of only the Abu Dhabi final.
Fittipaldi said: “It is a great honor and a very important step in my career to join the Red Bull family, the reigning F1 champions.
“I am very grateful for this opportunity and I would like to thank Red Bull, Dr Helmut Marko and Christian Horner for their confidence in me.”

Asked by TBEN what was attractive about Fittipaldi, Marko made it clear that the 21-year-old had accomplished a lot at Charouz.
“That he performed in a midfield team, I would say,” he said. “He was always there at the top. I think he had his ups and downs. And now he knows there is an opportunity. He will be with Carlin, which is a top team. And he is a character.”

Asked about the target for 2023, he said: “We will see how he performs. As always, with results.”
Marko confirmed that not all Red Bull’s 2022 F2 drivers will remain in the program next year.
“We’ll be making an announcement pretty soon about who’s leaving and who the new guys are.”
Meanwhile, Marko emphasized that Liam Lawson will benefit from his planned move to Japan for 2023.
“He will do Super Formula. It’s a difficult place to be. The Japanese drivers know every inch, they know all the tracks, it’s not easy.”
He also confirmed that Norwegian F2 racer Dennis Hauger will be elevated to an F1 reserve role next year, alongside Lawson, who will not always be available due to collisions over the race weekend.
“We have several reserve drivers. Another will be Hauger, that’s what has been decided so far. And we will see how it goes at the beginning of the season. There will be some clashes, but of our youngsters there will be two or three to be. “
