Folha de S. Paulo, known simply as Folha (Portuguese pronunciation: [ˈfoʎɐ], Sheet), is a Brazilian daily newspaper founded and continuously published in São Paulo since 19 February 1921. Owned by the Frias de Oliveira family since 1962, it has Brazil's largest circulation since 1986. Alongside O Globo and O Estado de S. Paulo, Folha is considered one of the most influential newspapers in the country.

The newspaper is considered to have played a major role during the military dictatorship. With the return of press freedom, it became an important channel for public expression. Folha also had an important role during the impeachment of President Fernando Collor de Mello in 1992. It has a partnership with Wikileaks to publish the United States diplomatic cables in the country, alongside O Globo.

Nevertheless, Folha's circulation has been on a sharp decline since the past decade. In December 1998, it led the circulation of Brazilian newspapers with an estimated 513,000 copies printed daily. Ten years later, its circulation was estimated at 299,000 copies, which represents a decrease of 41%, although it stills leads the newspaper market, which has been facing a decline as a whole.
