Slovenian Railways (Slovene: Slovenske železnice, SŽ), the state railway company of Slovenia was created in 1991 from the Ljubljana division of the former Yugoslav Railways after the breakup of Yugoslavia.

Slovenia is a member of the International Union of Railways (UIC). The UIC Country Code for Slovenia is 79.

Slovenian Railways operates 1,229 km of standard gauge tracks, 331 km as double track, and reaches all regions of the country. Slovenia is well connected by rail to all surrounding countries, reflecting the fact that it used to be part of the Austro-Hungarian Empire and later part of Yugoslavia. Left-hand running is used on double-track sections, unlike the remainder of the former Yugoslavian railways.
