János Barlabássy de Csesztve (Hungarian: csesztvei Barlabássy János; 1482–1560) was a Hungarian prelate in the first half of the 16th century. As a loyal partisan of King John Zápolya, he served as de facto the last Bishop of Csanád between 1537 and 1552, before the Ottoman Empire conquered the southern parts of the Kingdom of Hungary, including the whole territory of the diocese.
