Renault will be re-branded as Alpine for next year's Formula One campaign.
Fernando Alonso is returning to the sport following a two-year absence and his team will adopt the colours of the French national flag - red, white and blue.
Alonso, 39, won back-to-back world championships racing for Renault in 2005 and 2006.
Renault team principal Cyril Abiteboul said: "This change comes at a key moment in the trajectory of the team and the sport.
