The Lisbon Metro (Template:Lang-pt) is the metro (subway) system that provides Lisbon, Portugal with mass-transit services. It was the first subway in Portugal.

As of 2007, the four Lisbon subway lines total about 39 kilometres (24 mi) in length and comprise 46 stations.

Construction was started on 7 August 1955, and actual service began on 29 December 1959 with a Y-shaped line with two branches starting at Sete Rios (now Jardim Zoológico) and Entre Campos that joined at Rotunda (now Marquês de Pombal) to continue to Restauradores in the city centre. The total track length was then 6.5 kilometres (4.0 mi). In subsequent years the northern branches were extended in several steps to Colégio Militar (now Colégio Militar-Luz) and Campo Grande, respectively. The southern branch was extended via Rossio, Anjos and Alvalade to finally form a loop at Campo Grande. In 1995 the station at Marquês de Pombal was reconstructed to split the network into two lines, the Blue Line (linha Azul) from Colégio Militar-Luz to Campo Grande and the Yellow Line (linha Amarela) from Campo Grande to Marquês de Pombal.In May 1998 a third line, the Red Line (linha vermelha) was opened to connect Alameda to the exhibition grounds of the Expo 98 at Oriente.

The Blue line was split into two; it now ends at Santa Apolónia; the section until Campo Grande has become the Green Line (linha Verde) with a new terminus at Cais do Sodré. In 2004 the Blue, Yellow and Green lines were further extended to end at Amadora Este, Odivelas and Telheiras, respectilvely. As of 2005, total track length is 36.9 kilometres (22.9 mi). On December 19th 2007 the Blue line was extended to Santa Apolónia.

In August 2009 the extension of the Red Line to São Sebastião via Saldanha station was opened, making it possible to go from any line to another without changing trains more than once. An extension to Lisbon Portela Airport has been announced which has caused controversy as the airport is scheduled to be replaced in about 10 years, and might reduce the usefulness of the station, depending on the future usage of the area.

Once these extensions are completed to system will be served by 52 stations and will be 40 kilometres (25 mi) long.

Extensions to the Green and Yellow lines are also being studied.
