The Church of Saint Emerentiana on Tor Fiorenza (Italian: Santa Emerenziana a Tor Fiorenza, Latin: S. Emerentianae ad locum vulgo Tor Fiorenza) is a Roman Catholic titular church in Rome, built as a parish church, by decree of Cardinal Francesco Marchetti Selvaggiani. It is named for Saint Emerentiana, a 4th-century martyr. On 5 March 1973 Pope Paul VI granted it a titular church as a seat for Cardinals.

At present the Titulus Sancta Emerentianae ad locum vulgo Tor Fiorenza is held by Jean-Pierre Kutwa.

The facade has three doors which are framed by travertine marble. The church has three naves separated by pillars, with six side chapels. The apse is dominated by a large mosaic depicting the Triumph of the Church, by the Franciscan Belluno Ugolino.
