Pasquale Villari (3 October 1827 – 11 December 1917) was an Italian historian and politician.
In 1869 he was appointed under-secretary of state for education, and shortly afterwards was elected member of parliament, a position which he held for several years. In 1884 he was appointed senator, and became vice-president of the senate in 1887. In 1891-1892 he was minister of education in the Marchese di Rudini's first cabinet, and introduced valuable reforms into the curriculum of the schools. In 1893-1894 he collected a number of essays on Florentine history, originally published in the Nuova Antologia, under the title of I primi due secoli della storia di Firenze, and in 1901 he produced Le Invasioni Barbariche in Italia, a popular account in one volume of the events following the dissolution of the Roman empire.
