The Porsche Cayenne is a series of cars manufactured by the German company Porsche since 2002. It is a full-size luxury SUV. The first generation was known internally within Porsche as the Type 9PA or E1. It is the first V8-engined vehicle built by Porsche since 1995, when the Porsche 928 was discontinued. It is also Porsche's first off-road variant vehicle since its Super and Junior tractors of the 1950s, and the first Porsche with four doors.

The second-generation Cayenne (Type 92A or E2) was unveiled at the 2010 Geneva Motor Show in March following an online reveal. The Cayenne shares its platform, body frame, doors and electronics with the similar Volkswagen Touareg and Audi Q7. It received a facelift in 2014 with minor external changes, and introduced a new plug-in E-Hybrid version, with its public launch at the Paris Motor Show. Since 2008, all engines have featured direct injection technology. The third generation (Type PO536) was unveiled in 2017 at Stuttgart.

The Cayenne is the first Porsche assembled outside of Europe, in Kulim, Kedah, Malaysia. Only the base model 3 liter V6 is assembled in Malaysia, while other models are imported from Slovakia.
