Michele Amari (July 7, 1806 – July 16, 1889) was an Italian patriot and historian. Born at Palermo, he devoted a great part of his life to the history of Sicily, and took part in its emancipation. Amari was also an Orientalist; he is famous for throwing light on the true character of the Sicilian Vespers; and served as the Kingdom of Italy's first minister of public education.

Amari became an important figure during the Risorgimento. He was a link between Prime Minister Camillo Benso di Cavour and influential Sicilians, helping to convince them to support Italian unification. Amari did so expecting Cavour to grant Sicily some regional autonomy after unification.

Amari's historical works focus on Medieval Sicilian history, including extensive works on the period of Muslim control. His efforts have earned him acknowledgment as one of 19th century Europe's premier translators of Medieval Arabic writings. His Storia dei Musulmani di Sicilia (History of the Muslims of Sicily) (1854) is perhaps his greatest work. It has been translated into many languages, including Arabic by a group of Egyptian scholars in 2004.

He died at Florence in 1889.
