Leonforte (Sicilian: Liunforti) is an Italian comune with a population of 14,046 in the Province of Enna, Sicily. The town is situated 22 km from Enna, in the centre of the Erean Mountains at 600 metres a.s.l.

The ancient settlement of Tabas or Tavaca stood in the approximate location of Leonforte. During the Byzantine period of Sicily, and later under the Muslim Emirate of Sicily, a castle was built with a farmhouse in its vicinity. Irrigation systems were introduced and many mills took advantage of the abundance of water. In 1610 Nicolò Placido Branciforti founded a city, naming it Leonforte in tribute to his family's coat of arms; a lion holding a banner with the motto in fortitudine bracchii tui.
