Abraham Woyna (also known as Abraham Wojna) was a Roman Catholic priest and a bishop of Samogitia (1626-1631) and then of Vilna (1631-1649). His term in office was marked by the rise of Calvinism in the Polish-Lithuanian Commonwealth, to which he actively opposed. Among his achievements was the foundation of the monasteries of the Discalced Carmelites and the Good Friars in Vilna (modern Vilnius, Lithuania), the latter of which also opened up a hospital and a pharmacy nearby.
