Francis Xavier Krautbauer (January 12, 1824 – December 17, 1885) was a German-born prelate of the Catholic Church who served as the second bishop of the Diocese of Green Bay in Wisconsin from 1875 until his death in 1885.

While in Regensburg, Bishop John Timon of the Diocese of Buffalo recruited Krautbauer to immigrate to the United States.

St. Peter's served the local German Catholic community, who long fought against Krautbauer and Church leadership for control of the parish.

[3] On February 12, 1875, Krautbauer was appointed by Pope Pius IX to succeed the late Joseph Melcher as bishop of the Diocese of Green Bay.

[3] He oversaw the planning and construction of St. Francis Xavier Cathedral (modeled after Ludwigskirche in Munich), laying the cornerstone in 1876 and consecrating in 1881.
