The Oslo tram network (Norwegian: Trikken i Oslo, short from elektrikk=electric), is the 131.4-kilometre (81.6 mi) tram system in Oslo, Norway. It consists of six lines with 99 stops and has a daily ridership of 132,000. It is operated by Sporveien Trikken AS, a subsidiary of the municipal owned Sporveien who maintain the track and 72 tram vehicles on contracts with the public transport authority Ruter. The system operates on standard gauge and uses 750 V DC overhead. Depot, workshops and headquarters are at Grefsen (at the terminus of lines 13 and 17). There is also a depot at Holtet (along lines 18 and 19) that is home to the technical company InfraPartner, which maintains the track for the tram and metro systems in Oslo, and a small Office building for Oslo Sporveier.

The first tram in Oslo was opened in 1875 with a short line between Homansbyen west of the city centre, Oslo West Railway Station and a sideline to Grønland, east of the city centre. The first "trams" were in fact horse-drawn vehicles on flanged steel wheels. The first expansion of the line came in 1878 with a line to Grünerløkka just north-east to the city center.

Electric tram service was initiated in 1894 with a line over Briskeby to Majorstuen, a route south of the original Homansbyen line. Horsedrawn service was entirely replaced with electric service in 1900. For a long time, there were two tram companies operating in Oslo, "Grønntrikken" ("The Green Trams" with a green and yellow livery) and "Blåtrikken" ("The Blue Trams" with a blue livery). These companies were merged in 1924. During the 1910s, 1920s and 1930s, the network continued to expand, with the most notable addition being the construction of Ekebergbanen, a line up along the hill along the east side of the Oslo Fjord, south of the city. It was operated by a separate company. It was originally built to Sæter in 1917, the line was completed to Ljabru in 1941. The tram network reached its greatest extent in 1939 with the opening of the northeastern line to Sinsen.
