Viaduto do Chá ("Tea Viaduct") is a viaduct of São Paulo, Brazil. It was the first viaduct built in the city, and was instigated by Jules Martin, a French immigrant to the city. The 240-metre (790 ft) span crosses the Vale do Anhangabaú. Originally conceived in 1877, construction started in 1888 before being stopped one month later by a court case brought by local residents. Construction resumed in 1889, and the iron bridge was completed in 1892. The original viaduct was replaced in 1938 with a new concrete span. It often appears in TV interviews, as well as films and telenovelas set in São Paulo.

The viaduct is located in São Paulo, Brazil. It runs over the Anhangabaú River in the Vale do Anhangabaú valley, which separated two cities. On one side was the city centre of São Paulo, which ended at the Rua Direita. On the other side was a neighbourhood called "Morro do Chá" (now Republica and Consolação), which lacked good transportation and policing. In order to get between the two, a long tram ride in a 'U'-shape around the valley was required, or to go down a steep descent to the Ponte do Lorena and cross there, returning up a slope on the other side near to Rua Xavier de Toledo. An extension of the city's tram network to Consolação was proposed in 1879, but was rejected by local residents as being good for the tram company but bad for local residents.
