The Graz tramway network is a network of tramways forming an important part of the public transport system in Graz, which is both the capital city of the federal state of Styria, Austria, and the second largest city in Austria.

As of 2012[update], the Graz tram network ran on an almost 60 kilometres (37 mi) of route, and served 53.56 million passengers.

The trams form part of the styrian integrated fare system which covers all modes of public transport in Graz and Styria.

The Tramway Museum Graz, at the terminus of line 1 in Mariatrost, holds many exhibits relating to the system.

The area around Jakominiplatz was developed as the main tram and city bus interchange from 1995, whilst extensions to Puntigam, Liebenau/Murpark and St Peter followed in 2006 and 2007.

Zone 101 tickets are valid on all trams, and all city buses with single or double digit route numbers.

On February 5, 2018, the co-financing of a comprehensive expansion program was signed between the city of Graz and, for the first time, the province of Styria.

Starting 2025 15 new vehicles of the type Flexity from the manufacturer Alstom are supposed to enter service.
