Pope Leo XIV has appointed Monsignor James A. Misko, a priest of the Diocese of Austin, Texas, as the next bishop of Tucson, Arizona.
The Holy See Press Office publicized the appointment at the Vatican, and it was also publicized in Washington, D.C., on Dec. 22 by Cardinal Christophe Pierre, apostolic nuncio to the United States. Misko has been serving as vicar general and moderator of the curia for the Diocese of Austin.
Misko, 55, was born June 18, 1970, in Los Angeles. He earned a bachelor’s degree in communications from St. Edward’s University in Austin and later completed priestly formation and graduate theological studies in Houston, including a master of divinity degree at St. Mary’s Seminary. He was ordained a priest for the Diocese of Austin on June 9, 2007.
Before entering seminary, Misko worked in the restaurant industry from 1991 to 2000, according to biographical information shared by the U.S. Conference of Catholic Bishops.
His priestly assignments have included service as parochial vicar at St. Elizabeth of Hungary Parish in Pflugerville (2007–2010) followed by leadership at Christ the King Parish in Belton — first as administrator (2010–2011) and then as pastor (2011–2014). He later served as pastor of St. Louis King of France Parish in Austin (2014–2019).
In 2019, Misko was named vicar general and moderator of the curia for the Diocese of Austin. In 2025, he also served as diocesan administrator of the diocese, a role he held from March to September.
Misko is a native English speaker and is also proficient in Spanish.
He succeeds Bishop Edward Joseph Weisenburger, who served as bishop of Tucson beginning in 2017 and was appointed archbishop of Detroit in February.
