Jan Hasištejnský of Lobkowicz (Czech: Jan Hasištejnský z Lobkovic, Czech pronunciation: [ˈjan ˈɦasɪʃtɛjnskiː ˈzlopkovɪts]; 1450[1]–1517) was a Bohemian diplomat of the House of Lobkowicz.
[2] He undertook diplomatic missions to Luxembourg (in 1477) and Rome (in 1487) in the time of King Vladislaus II.
The king sent him to negotiate a marriage with Mary of Burgundy, which was ultimately unsuccessful.
He made a journey to Palestine in 1493 and wrote a travel book about it, titled Pilgrimage to the Holy Grave in Jerusalem (first published in 1505).
[3] He was the elder brother of the so-called "Czech Ulysses" Bohuslav Hasištejnský z Lobkovic.
