The Porsche 986 is the internal designation for the first generation Boxster, a mid-engine two-seater roadster built by German automobile manufacturer Porsche.

The Boxster's name is derived from the word "boxer", referring to the vehicle's flat or "boxer" engine, and the name "speedster", first seen on the 356. Powered by a 2.5-litre flat six-cylinder engine, the base model was upgraded to a 2.7-litre engine in the year 2000 and a new Boxster S variant was introduced with a 3.2-litre engine. In 2003, styling and engine output was upgraded on both variants. The 986 was succeeded by the 987 which retained the Boxster roadster and added the Cayman fixed-roof coupé body style.

In addition to the coupé and cabriolet versions, Targa versions of the Carrera 4 and Carrera 4S were also available, which carry on with the "glass canopy" roof design used since its first application on the 993 until the 991, which reverted to the classic targa top layout used on the early 911 Targas.
