Line 4 (Yellow) (Portuguese: Linha 4-Amarela) is a line of the São Paulo Metro, originally called Southeast-Southwest Line. When finished, it will go from Luz to Vila Sônia. The first stretch, between and Faria Lima and Paulista stations, opened on May 25, 2010. Two other stations, Butantã and Pinheiros, were opened in July 2011. Today, the line goes from Butantã to Luz. It is expected that the line will be fully completed by 2015. It is operated by ViaQuatro, a private company which won the public-private partnership to operate Line 4 for 30 years, which can be renewable for another 30 years. Companhia do Metropolitano de São Paulo monitors the operation.

Conceived since the years 1940s, the route of Line 4-Yellow was present in all studies for deployment of the Metro in São Paulo since. This road was consolidated in 1968 when the initial studies for the implementation of the current subway network, receiving at that time, the name of Southeast-Southwest Line. In parable form, would connect the neighborhoods of Pinheiros and Sacomã, from Jóquei Clube station to Via Anchieta station, through the Downtown, cutting East-West line of the Metro in República and Pedro II stations. Integration platforms came to be built in those two stations, but were not used. The Republic station platforms, built in the 1980s, with a further configuration of line 4, would be demolished for the passage of the tunneling machine, equipment that built the tunnel of Line 4 between Faria Lima and Luz stations, those from Pedro II station became a depôt. The consolidation of the project was only in 1993, when the basic design was first developed, already no longer including the Southeast portion, embedded in other policies of the Metro expansion and improvement of commuter trains.
