It has not yet been decided which team will use the engines next season - Red Bull Racing or Scuderia Toro Rosso.
Scuderia Toro Rosso use Cosworth engines this season, while Red Bull Racing are powered by Ferrari.
"It is positive for F1 to have another team with a top-line engine, and this agreement will also reinforce our presence in the sport," said Renault.
"We look forward to working with a dynamic, ambitious company such as Red Bull."
Red Bull Racing have a contract to continue with Ferrari engines next season.
But they may seek to pass that supply on to their Italian-based sister team, who have Italian Vitantonio Liuzzi as one of their drivers.
Renault engines powered Lotus, Ligier, Tyrrell, Williams and Benetton cars in the 1980s and 1990s, winning 80 Grands Prix.
