The Stadler Eurolight (known as the Vossloh Eurolight until 2015) is the brand name for a family of 4-axle Bo'Bo' mainline diesel-electric locomotives with sub-20-tonne axleloads for passenger and freight trains produced by Stadler Rail.

The Eurolight series was announced by Vossloh during 2009, the first examples were completed and commenced testing in the following year. The type has been intentionally developed to support use on secondary lines without limiting power or speed performances, making it suitable for mixed traffic operations. Specific versions of the Eurolight have been developed for the United Kingdom market, and a 6-axle Co'Co' machine for narrow gauge Asian markets, named UKLight and AsiaLight respectively. Furthermore, an electro-diesel locomotive derivative of the UKLight that shares much of its design, referred to as the Stadler Euro Dual, has also been developed and introduced during the late 2010s.
