John I Albert (Polish: Jan I Olbracht) (27 December 1459 – 17 June 1501) was King of Poland (1492–1501) and Duke of Głogów (1491–1498).

John was the third son of Casimir IV, King of Poland, and Elisabeth, daughter of the King Albert of Hungary. As crown prince, he distinguished himself by his brilliant victory over the Tatars at Kopystrzyń (1487). In 1490, the Hungarian nobility proclaimed John King of Hungary at the Rákos diet. He was, however, defeated by his brother, King Vladislaus II of Hungary. In 1492, John succeeded his father as King of Poland thanks to the key intervention of his brother Friedrich Jagiellon, archbishop of Kraków and archbishop of Gniezno. Friedrich achieved the coronation of John. However, losses of revenue due to the secession of Lithuania placed John at the mercy of the Polish sejmiks, or local diets, where the szlachta, or local nobles, made their subsidies dependent on the king's subservience.

John desired to pose as the champion of Christendom against the Ottoman Turks. Circumstances seemed, moreover, to favor him. In his brother Ladislaus, who as King of Hungary and Bohemia possessed a dominant influence in central Europe, he found a counterpoise to the machinations of Emperor Maximilian I, who in 1492 had concluded an alliance against him with Ivan III of Muscovy. As suzerain of Moldavia, John was favorably situated for attacking the Turks. At the conference of Leutschau (1494), the details of the expedition were arranged between the kings of Poland and Hungary and Elector John Cicero of Brandenburg, with the co-operation of Stephen III of Moldavia, hospodar of Moldavia, who had appealed to John for assistance.
