Ban Kulin (1163–1204) was a notable Bosnian Ban who ruled from 1180 to 1204, first as a vassal of the Byzantine Empire and then, most importantly, of the Banate of Bosnia. He was one of Bosnia's most prominent and notable historic rulers and had a great effect on the development of early Bosnian history. One of his most noteworthy diplomatic achievements is widely considered to have been the signing of the Charter of Ban Kulin. His son, Stjepan Kulinić succeeded him as Bosnian Ban. Kulin founded the House of Kulinić.

Kulin came to prominence in Bosnia 1163 as he was under the Byzantine Emperor Manuel I Comnenus who was just taking the country from the Hungarians earlier, although it would not be until 1180 that he would place Kulin as his vassal as Ban.

His rule is often remembered as being emblematic of Bosnia's golden age, and he is a common hero of Bosnian national folk tales. Under him, the "Bosnian Age of Peace and Prosperity" would come to exist. Bosnia was completely autonomous and mostly at peace during his rule.
