Jean Hurault de Boistaillé (1517–1572) was a French nobleman and government official. In 1558 he was an emissary of the king Henry II, then ambassador of France in Constantinople and Venice (1562–1564). He played an important role in getting military support from the Ottoman Empire in the Italian War of 1551–1559. He was a bibliophile and collector of manuscripts and incunabula. He died in England in 1572 during his diplomatic mission. Some of Huralt’s manuscripts are housed now at the University of Leiden; one manuscript is housed in Bern (Burgerbibliothek Bern, ms. 360).
