The Chevrolet Express (also known as the GMC Savana) is a series of full-size vans produced by General Motors since 1996. The successor to the Chevrolet G-series van, the Express is produced in passenger and cargo variants. Alongside the standard van body, the line is offered as a cutaway van chassis; the latter vehicle is a chassis cab variant developed for commercial-grade applications, including ambulances, buses, motorhomes, and small trucks.

In production for a single generation since 1995, over 2.5 million examples of the Express and the Savana have been produced. One of the longest-produced designs in American automotive history, the Express/Savana are rivaled only by the Jeep Wagoneer and Dodge Ram Van for longevity.

Since 1995, General Motors has assembled the Express and Savana at its Wentzville Assembly facility (Wentzville, Missouri). Also, since 2017, GM has sourced commercial cutaway-chassis production from Navistar through its Springfield Assembly Plant (Springfield, Ohio).
