Claes Janszoon Vooght (c. 16?? – 1696) was a Dutch surveyor, mathematician, teacher, and geographer active in Amsterdam during the second half of the 17th century. Most of his work is associated with the nautical charts of Johannes van Keulen, particularly the Zee-Fakkel, for which he composed most of the text and many of the charts. In addition to his work with the Keulen firm, he was a well respected teacher of navigation.
