Marta Teresa Smith de Vasconcellos Suplicy (Portuguese pronunciation: [ˈmaʁtɐ supliˈsi]; born 18 March 1945) is a Brazilian politician and psychologist.

She later served as the Brazilian Minister of Tourism between 14 March 2007, and 4 June 2008, when she resigned to run again for the mayoralty of São Paulo.

In the public educational system she created large schools and cultural centers, called "CEU", which were built in the poorest districts of the city.

On 14 March 2007, Suplicy accepted the Luiz Inácio Lula da Silva's invitation to become the new Minister of Tourism.

[3] Later that same year, on 13 June 2007, when interviewed about the 2006–2007 Brazilian aviation crisis, Suplicy suggested that users of the Congonhas Airport in São Paulo who suffered long delays while heading for vacation should "relax and enjoy because they will forget the troubles afterwards" (Portuguese: "relaxa e goza porque você vai esquecer dos transtornos."[4]).

From 1965 to 2001, she was married to Eduardo Suplicy, a PT Brazilian senator from the state of São Paulo who is the father of her children.
