TheStockholm tramway network forms part of thepublic transport system inStockholm, thecapital city ofSweden.

Beginning withhorse trams in 1877, the Stockholm tram network reached its largest extent in 1946. Many of the former suburban tram lines became parts of theStockholm Metro between the years 1950-1964. In September 1967, in conjunction with theSwedish switch from left-hand to right-hand traffic, the last parts of the once large inner city street running tram network were closed. What little remained of the former network following 1967 were isolated suburban feeder lines to the Metro.

However, in 1991 a 3 km (1.9 mi) long heritage line opened to the recreational areaDjurgården; and in 2000, the non-radial half-circle lineTvärbanan opened with articulated low floor vehicles connecting an inner ring of Metro andcommuter rail stations just outside theinner city proper, with subsequent extensions in 2003 and 2014; and in 2010 theheritage line was extended and converted to a regular service line.

The first tramway in Stockholm was opened on 10 July 1877 and was drawn by horses. A tramline run on steam-power opened in 1887. Stockholm's tram network was converted to electrical propulsion 1901-1905. An extensive network formed in the early 20th century. Trams were effectively replaced by theStockholm Metro from 1950 onwards, and most tram lines were closed down by September 1967 due to the effect ofDagen H and replaced with buses (especially those in Stockholm proper), with the exception of two suburban tram lines,Lidingöbanan andNockebybanan.

In 1991, one tram line,Djurgårdslinjen, was reopened as a heritage and tourist line. Since 2000, two more tram lines have been built,Tvärbanan (line 30 – formerly 22), a peripheral line linking the southeastern suburb ofSickla with the northwestern suburb ofSolna, and an extension of Djurgårdslinjen into the inner citySpårväg City (line 7). The Tvärbana was extended in 2013, and will be further extended in the future.

As of January 2023, the following lines provide service in theStockholm metropolitan area:^[1]

While all tramlines run on standard gauge track and use the same overhead voltage (750 V DC), thecab signalling system for Lidingöbanan is different from the one for Tvärbanan, making rolling stock incompatible. The other tramlines (Nockeby and City/Djurgården) have no cab signalling requirement.
