Antony IV (? – May 1397) was the Ecumenical Patriarch of Constantinople for two terms, from January 1389 to July 1390, and again from early 1391 until his death. He was originally a hieromonk, possibly from the Dionysiou monastery in Mount Athos. He was deposed during the usurpation of John VII Palaiologos in April 1390, and replaced by Macarius, who had already served in the office in 1377–1379. After the restoration of John V Palaiologos and Manuel II Palaiologos a few months later, he was restored to his post.
