The S-series is a family of compact cars from the Saturn automobile company. This was the first series of Saturn vehicles. The automobile platform used, Z-Body, was developed entirely in-house at Saturn and shared very little with the rest of the General Motors product line.

The original S series was marketed from the fall of 1990 through the end of the 2002 model year, with a redesign in 1996.

The S-series line-up included sedans (SL, SL1, SL2), coupes (SC, SC1, SC2) and wagons (SW1, SW2). In the late 1990s right hand-drive versions were exported to Japan. Two engines, unique to Saturn, were available. They were the SOHC and DOHC fours, each 1.9 liters in displacement. A change partway through the 1999 model year gave the SC a suicide door.

The S-series was replaced with the Saturn ION in 2003.
