The Alfa Romeo C43 is a Formula One car designed and built by Alfa Romeo competing in the 2023 Formula One World Championship.

The car is driven by Valtteri Bottas and Zhou Guanyu, both in their second year at the team.

Design and development
On 26 August 2022, Alfa Romeo announced that they would leave Formula One at the end of 2023, ending their partnership with Sauber, making C43 the last Sauber-engineered car to be badged as an Alfa Romeo. On 20 January 2023, it was announced that the C43 would be launched on 7 February.

Launch and pre-season testing 
Alfa Romeo revealed their car design on 7 February 2023 via livestream. The car donned a new red-and-black livery, representing the departure of the previous year's title sponsor (Orlen Unipetrol) and the entry of global digital brokerage platform Stake.com taking said role. However, in countries where advertisement of gambling and sports betting is disallowed, and in the video game F1 23, Stake's branding will be replaced by one of streaming website Kick. If both sponsorships are outlawed, and in its appearance in the video game F1 22, the Alfa Romeo logo will be featured. The Kick sponsorship was first showcased at the 2023 Australian Grand Prix.

Prior to the season opener at Bahrain, the C43 was added to the video game F1 22.
