Butera (Sicilian: Vutera) is an Italian town and a commune in the province of Caltanissetta, in the southern part of the island of Sicily.

Pace himself has asserted that the term, aside from boutherès, may derive also from the Graeco-Byzantine word patela (plain), which refers to Butera's location.

[7] In the area of "Piano fiera" (a new neighborhood built below the old town) where a prehistoric necropolis still stands, is a construction called "dolmen cysts" made of stone slabs assembled in cubiform manner (a style found also throughout Sardinia).

Following the fall of Butera to the Normans in 1091,[13] the town's Muslim leaders were resettled in Calabria to prevent them from fomenting rebellion among the rest of the population.

Settlers from Northern Italy (including Lombardy, Piedmont, Liguria and Emilia-Romagna) as well as southern France migrated to the county,[9] which is reflected in the presence of Gallo-Italic dialects which are still spoken in certain Sicilian towns such as Piazza Armerina and Aidone.

[20] In 1392, the Alagona family lost possession of the County following their defeat by Martin I, and was passed to the Catalan prince Ugo of Santapau.

[20] In Butera, 12–13% of the population carries the sickle-cell trait, and its prevalence amongst the town's citizens is believed to be due to selective pressure against malaria.
