Guillaume Levasseur de Beauplan (c. 1600 – 6 December 1673) or William le Vasseur de Beauplan was a French-Polish cartographer, engineer and architect.
Beauplan is best known for his maps of Ukraine (which he spelt as Ukranie or Vkranie, with the "U" spelt as a "V"), and his 1660 book Description d'Ukranie ("Description of Ukraine"), first published in 1651 as Description des contrés du Royaume de Pologne ("Description of the Kingdom of Poland's Lands"), which was republished and translated many times in Western European languages throughout the rest of the 17th century and the entire 18th century.[1]
