Grotti is a luxury-sports car manufacturer featured in the GTA series based on the real-world Italian automotive company Ferrari S.p.A. Throughout the series, the company features the Turismo, the Cheetah, and the Jetmax. Grotti has dealers in Rodeo, Los Santos in Grand Theft Auto: San Andreas and in Algonquin, Liberty City in Grand Theft Auto IV. Breaking into a Turismo in Grotti's Algonquin showroom (GTA IV) will give the player a one-star wanted level.

Grotti in Italian means coves, or sea inlets, but is presumably a play on the English word grotty, meaning seedy. Grotti's logo caricatures Ferrari's prancing horse. In GTA San Andreas the logo has a prancing rabbit/hare and in GTA IV the logo has a horse sitting down. Grotti's logo in GTA V has been changed.
