The Osijek tram system is operated by the City Transport of Osijek (GPP Osijek) and serves the city of Osijek, capital of the Slavonia region of Croatia.

The Osijek network is the only tram system still in existence outside Zagreb. Services have operated continuously since the first horsecar tram line was opened in 1884 (connecting the railway station and city square), and the first electric tram ran in 1926.

The present network consists of two lines which intersect in the city square (Trg Ante Starčević) and the fleet consists of refurbished Tatra T4 vehicles. All tracks are at 1000mm (narrow gauge) width.
