Paul I Šubić of Bribir (Croatian: Pavao I. Šubić Bribirski, Hungarian: bribiri I. Subics Pál; c. 1245 – 1 May 1312) was Ban of Croatia between 1275 and 1312, and Lord of Bosnia from 1299 to 1312. As the oldest son of Stephen II of the Šubić noble family, he inherited the title of count of Bribir. He was appointed ban in 1273. He was relieved from duty in 1274, following his involvement in disputes between the Dalmatian coastal cities of Trogir and Split, and was returned to office in 1275.
With the help of his brothers, Mladen I and George I, Paul imposed direct rule over most of the coastal cities. The contest over the lands of the Kačić family in southern Croatia, who were known for piracy in the Adriatic Sea, brought Paul into conflict with the Republic of Venice. At the same time, the Šubićs became allies with the House of Anjou from Naples. Fighting with Venice continued intermittently until a peace treaty in 1294.
