WaveRunner is a trademarked name and type of personal water craft (PWC) produced by the Yamaha Motor Company.

In 1990, the WaveRunner III 650 (Marine Jet 650TL) was the first personal watercraft to offer a three-person seat and reverse.

The WaveRunner VXR650 (Marine Jet 650TX) was released as the deluxe model of Yamaha's tandem series. While the same size as the initial WaveRunners, the adoption of a new concave hull design gave it sharper turning with reduced slipping.
