Demeter Naprágyi (Náprágyi, Napragyi, Napraghy or Napragi; 1564 – before 5 March 1619)^[1] was a Hungarian prelate of the Roman Catholic Church, who served as bishop of several dioceses. He was the Archbishop of Kalocsa from 1608 to 1619. He also functioned as Chancellor of Transylvania between 1598 and 1600.

Naprágyi was born into a noble family from Gömör County (since the 18th century: Gömör és Kis-Hont County) and raised in the court of Bishop of Pécs Miklós Telegdi. He studied theology in Vienna with the aid of the bishop. After ordination, he became director of the Nagyszombat College (today: Trnava, Slovakia). He was appointed Canon of Esztergom by bishop István Radéczy in 1586. Two years later, he served as Grand Provost of Eger. He was the Provost of Arad between 1593 and 1596. He became Bishop of Szerém (Syrmia) in June 1596. He held the office of Bishop of Transylvania since May 1597.

He often worked as envoy of his King, Rudolf. He visited Sigismund III Vasa in 1598. He had also good relationship with Sigismund Báthory.

He was elected Chancellor of Transylvania in 1598, during the reign of Prince Andrew Báthory. He also held the position, when Michael the Brave marched into Transylvania. He was a supporter of the Báthory family, as a result he was banished from Transylvania by the Diet of Gyulafehérvár (today: Alba Iulia, Romania) in January 1601. He carried the herma of Saint Ladislaus and his valuable book collection when left the principality. His episcopal property was seized by the diet.

From 1602, he was the Provost of Pozsony (Pressburg; today: Bratislava, Slovakia). He functioned as Bishop of Veszprém since August 1605 and as Bishop of Győr since December 1606. He was elected Archbishop of Kalocsa in 1608. After the death of Ferenc Forgách (1615), he applied for the position of Archbishop of Esztergom, but failed to reach success: Péter Pázmány, the significant person of the Hungarian Counter-Reformation, was elected head of the Hungarian Roman Catholic Church.
