Antonio Bettini (13 June 1396 – 22 October 1487) was an Italian clergyman, diplomat and writer. Bettini was born in Siena in 1396. He joined the convent of San Girolamo in Siena in 1439 and worked closely with Pope Pius II. Pius made Bettini bishop of Foligno in 1461. For Pope Sixtus IV, Bettini may have travelled to France (1474) and Germany (1481). He retired to his original convent in Siena in 1486 and died a year later. Bettini was revered by later biographers and sometimes referred to as "Beato" (Blessed) (a step toward canonization), but this designation was never church-sanctioned.
