The Ostrava tramway network is the third largest tram network in the Czech Republic. The network is operated by Dopravní podnik Ostrava, a company wholly owned by the city of Ostrava that also runs the city's bus and trolleybus network. As of 2022, DPO runs 17 lines with a total route length of 231.5 kilometres (143.8 mi) on 62.7 kilometres (39.0 mi) of track. The network is a part of ODIS, the integrated public transport system of the Moravian-Silesian Region.
Most of the network is double-track and runs within the boundaries of the city. The only exception to both is Line 5 between Poruba and Budišovice, which runs on a single-track section with two sidings and is one out of two remaining single-track tram lines in the Czech Republic that is in regular operation, the other being the interurban line between Liberec and Jablonec nad Nisou.[citation needed]
