Athanasius of Brest (secular name Afanasy Filippovich) was a seventeenth-century Eastern Orthodox hieromonk, hegumen, and martyr associated with the defense of Orthodoxy in the Polish-Lithuanian Commonwealth. Contemporary documentation of his birth and parentage is lacking; later hagiographical tradition dates his birth to approximately 1597 and places it in the Belarusian territories of the Grand Duchy of Lithuania. He is known to have studied at the school of the Orthodox Holy Spirit Brotherhood in Vilnius, an important institution for Orthodox education after the Union of Brest.

He entered the monastic life at the Holy Spirit Monastery in Vilnius, receiving the name Athanasius, and was ordained a priest. He later became hegumen of the monastery at Kupiatichi and then of the Monastery of St. Simeon the Stylite in Brest. Athanasius emerged as a determined critic of the Union of Brest of 1596, which had created a Uniate church in communion with Rome while leaving a remaining Orthodox hierarchy. He traveled to Moscow to appeal to the tsar and appeared before the Polish king with petitions on behalf of the Orthodox population. He left a diary recording his journeys, encounters, and claimed visionary experiences, including appearances of the Mother of God exhorting him to struggle for the Orthodox faith.

In 1648, during the early stages of the Cossack uprising led by Bohdan Khmelnytsky, Athanasius was arrested by authorities in Brest. He was accused of fomenting unrest and of sympathy with the rebels. After detention, he was put to death on 5 September 1648. Accounts of the execution state that he was shot and subsequently killed with a bladed weapon; his body was thrown into a pit outside the city.

Relics attributed to him were recovered not long afterward and became objects of veneration, with reports of miracles. Athanasius was honored as a hieromartyr in Orthodox circles in the region and was eventually included among the saints of the Russian Orthodox Church. His principal feast day is 5 September. Surviving information about him derives largely from his own diary, later hagiographies, and the broader historical record of religious conflict in the seventeenth-century Commonwealth; many personal details remain uncertain.
