The Nikon S3 Limited Edition 2000, often called the S3 Millennium, is a 35mm rangefinder camera produced as a commemorative reissue of Nikon's original S3 from the late 1950s. It was sold as a low-volume collector's item to mark the year 2000 and uses the Nikon S bayonet rangefinder mount.

At UK auction, hammer prices for the S3 Millennium have sat in the £1,200–£1,400 range, with a median around £1,300 based on the limited sales record available today. As a low-production commemorative, value is closely tied to completeness: examples that retain the original box, paperwork and presentation packaging tend to sell for more than bare bodies, and condition of the chrome and rangefinder patch has a strong influence on what a clean example is worth.
