Anton Mrak (1739 - 1801), also known as Antoni Mrakh, was a Slovenian mining engineer, surveyor, and cartographer active in the late 18th century. He was born in Idrija, Slovenia, the son and apprentice of the legendary Jo┼żef Mrak (1709 - 1786), founder and the main representative of the so-called 'Idrija Cartographic School'. Works by Anton are few, but he did make a 1766 map of Istanbul / Constantinople and a 1784 geological map of Idrija's ore deposits.
