Nockebybanan is a tram line between Nockeby and Alvik in the western suburbs of Stockholm, Sweden.

Conversion happened in 1952, forming the western section of the present-day Stockholm metro Green Line.

Nockebybanan and Lidingöbanan were the only tram lines in the Stockholm region not to be withdrawn in conjunction with the switch to right-hand traffic in 1967.

[3] By the 1990s, the line and rolling stock was in a poor state of repair and was widely expected to be dismantled and replaced with bus services.

A running race in the surrounding neighbourhoods, Tolvanloppet takes both name and distance (12 km) from the line number.
