The Archdiocese of Milwaukee (Latin: Archidiœcesis Milvauchiensis) is a Latin Church ecclesiastical territory, or archdiocese, of the Catholic Church in southeast Wisconsin in the United States. The Archdiocese of Milwaukee is the metropolitan see of the ecclesiastical province of Milwaukee. It includes the suffragan dioceses of Green Bay, La Crosse, Madison, and Superior.

It was formed in 1843, with territory taken from the Diocese of Detroit. It was elevated from a diocese to an archdiocese in 1875. In 2011, the sexual abuse scandal in the Roman Catholic Archdiocese of Milwaukee resulted in its filing for bankruptcy.

Pope Francis named Jeffrey S. Grob as archbishop on November 4, 2024.

The Archdiocese of Milwaukee encompasses the City of Milwaukee along with the following counties:

Dodge, Fond du Lac, Kenosha, Milwaukee, Ozaukee, Racine, Sheboygan, Walworth, Washington and Waukesha.

The first Catholic presence in present-day Wisconsin was that of French Catholic missionaries in the Green Bay area in the 17th century. When French explorer Jean Nicolet entered the Green Bay areas in 1634, he was followed by Jesuit missionaries. Wisconsin became part of the French colony of New France.

Reverend Claude-Jean Allouez celebrated Mass with a Native American tribe near present-day Oconto in December 1669, the feast of St. Francis Xavier. He established the St. Francis Xavier Mission there. The mission moved to Red Banks for a short time in 1671, and then to De Pere, where it remained until 1687, when it was burned. The missionaries worked with the Fox, Sauk, and Winnebago tribes, protected by Fort Francis near Green Bay. When the fort was destroyed in 1728, the missionaries left the area.

When the French and Indian War ended in 1763, the British took control of the Wisconsin area. During the 18th century, the few Catholics in Wisconsin were governed by the Diocese of Louisiana and the Two Floridas, based in New Orleans. After the American Revolution ended in 1791, the new United States took over Wisconsin.

Catholic jurisdiction for the new Wisconsin Territory passed to the Diocese of Bardstown in 1808, then the Diocese of Cincinnati in 1826. The first new Catholic church in the Wisconsin area in over 100 years was constructed in Fort Howard in 1825. Its parishioners included many French Canadians living in the settlement.

In 1833, the new Diocese of Detroit assumed jurisdiction over the area. In 1837, the missionary Reverend Florimund J. Bonduel traveled from Green Bay to visit the French fur trader Solomon Juneau in Milwaukee. While in Milwaukee, Bonduel celebrated the first mass in that city.

Later in 1837, the Diocese of Detroit sent Reverend Patrick Kelly to Milwaukee to serve as its first resident priest. Kelly celebrated mass in the Milwaukee courthouse until 1839, when he opened St. Peter's, the first Catholic church in the city. In 1841, Coadjutor Bishop Pierre-Paul Lefevere of Detroit visited Milwaukee.

In November 1843, Pope Gregory XVI erected the Diocese of Milwaukee, taking its territory from the Diocese of Detroit. The new diocese covered all of the Wisconsin Territory, including part of present-day Minnesota. The pope named Reverend John Henni from the Diocese of Cincinnati as the first bishop of Milwaukee.

When Henni took office, he only had four priests ministering to a few Catholics immigrants from Germany and Ireland. The only church in the diocese was St. Peter's, which was deeply in debt. Henni in 1845 founded St. Francis Seminary, allowing the seminarians to stay in his residence. He also brought several orders of nuns and priests to Milwaukee.

In 1846, Henni completed Old St. Mary's Church in Milwaukee, the second Catholic church in Milwaukee. Designed by architect Victor Schulte in the Zopfstil style, St. Mary's was built to serve German immigrants. The Annunciation altarpiece in St. Mary's, painted by Franz Xavier Glink was donated to the diocese by King Ludwig I of Bavaria. In 1847, Henni laid the foundation of the new cathedral, St. John the Evangelist. Also designed by Schulte, the cathedral was built with Cream City brick that was fabricated locally. St. John the Evangelist was consecrated by Archbishop Gaetano Bedini, the papal nuncio of the United States, in 1853.

In 1850, Pope Pius IX erected the Diocese of St. Paul, taking Minnesota from the Diocese of Milwaukee. In 1866, the same pope erected the Dioceses of La Crosse and Green Bay, removing their territories from the Diocese of Milwaukee.

In 1875, Pius IX elevated the Diocese of Milwaukee to the Archdiocese of Milwaukee, with Henni as first archbishop. In 1880, Bishop Michael Heiss of La Crosse was appointed coadjutor archbishop of Milwaukee by Pope Leo XIII to assist Henni. Heiss served as pastor of St. Mary's and rector of St. Francis Seminary. At Saint Francis, Heiss trained German-speaking priests to serve German Catholics of the archdiocese. In one of his last acts, Henni oversaw the opening of Marquette University in Milwaukee in August 1881. After Henni died two days later, Heiss automatically became the next archbishop of Milwaukee.

In 1889, the Wisconsin Legislature passed the Bennett Law which required all primary and secondary schools in the state to teach major subjects in English. The law was bitterly resented by German-American communities, both Catholic and Lutheran, that ran schools teaching in German. It was also opposed by Polish and Norwegian communities in Wisconsin. However, there was less opposition from Irish Catholics. The law was endorsed and promoted by the anti-Catholic American Protective Association. Heiss unsuccessfully fought the measure.

After Heiss died in 1890, Leo XIII named Bishop Frederick Katzer as the next archbishop of Milwaukee. At the beginning of Katzer's tenure in 1891, the archdiocese contained 227 priests, 268 churches, and 125 parochial schools to serve a Catholics population of 180,000.

Katzer strongly opposed the Bennett law. The outpouring of anti-Catholic sentiment from the law's supporters soon moved Irish Catholics against it. A prominent Irish newspaper, the Catholic Citizen, labeled the Bennett Law a convergence of "all the sectarian, bigoted, fanatical and crazy impurities" within the Republican Party which had taken the reins of power. When the Democratic Party regained power in Wisconsin, it repealed the Bennett Law in 1891.

When Katzer died in 1903, there were 329 priests, 321 churches, 148 parochial schools, and 280,861 Catholics in the archdiocese. Leo XIII replaced Katzer in 1903 with Bishop Sebastian Messmer of Green Bay. In 1921, he prohibited Catholic children in Milwaukee from participating in a Fourth of July pilgrim pageant, which he described as "exclusively a glorification of the Protestant pilgrims," but later withdrew his objections. Messmer drew criticism from Polish Catholics after condemning the Kuryer Polski newspaper in Milwaukee.

During his 26-year tenure, Messmer established Mount Mary College in Milwaukee and saw the elevation of Marquette College to Marquette University. He actively supported the American Federation of Catholic Societies as well as ministries for African American and Hispanic Catholics. Nearly 30 religious orders were founded in the archdiocese and charitable institutions were doubled during his administration. He founded the Catholic Herald, the official newspaper of the Archdiocese of Milwaukee, in 1922. Messmer died in 1930.

Following Messmer's death in 1930, Pope Pius XI that same year named Bishop Samuel Stritch from the Diocese of Toledo as fifth archbishop of Milwaukee. A fire partially destroyed the Cathedral of John the Evangelist in 1935. Stritch was an advocate for Catholic Action and the Catholic Youth Organization. An opponent of the controversial Charles Coughlin, he once wrote a letter to a Milwaukee rabbi in which he rebuked those who "gain and hold a popular audience, degrade themselves and abuse the trust reposed in them by misquoting, half-quoting, and actually insinuating half-truths." In 1939, Stritch was appointed archbishop of the Archdiocese of Chicago.

Pope Pius XII in 1940 appointed Bishop Moses E. Kiley of the Diocese of Trenton as the next archbishop of Milwaukee. Kiley oversaw an extensive renovation of the fire-damaged Cathedral of St. John the Evangelist, which reopened in 1942. He also rebuilt the St. Aemillian Orphanage in Milwaukee, which had also suffered major fire damage in the 1930s. Kiley renovated St. Francis Seminary, converted Pio Nono High School in St. Francis into a minor seminary, and created a Catholic Family Life Bureau in 1948. Kiley died in 1953.

Bishop Albert Meyer of the Diocese of Superior was appointed archbishop of Milwaukee by Pius XII in 1953. Five years later, in 1958, he became archbishop of Chicago. Pope John XXIII then named Bishop William Cousins from the Diocese of Peoria as the next archbishop of Milwaukee. During the American civil rights movement, Cousins was pressured to respond to the activities of Reverend James Groppi, an activist priest who led several civil rights marches and protests. In 1967, Cousins expressed his support for open housing and Groppi's other objectives, triggering a backlash from some Catholics in the archdiocese.

In 1971, Cousins sold a 180-acre tract of archdiocesan land to a commercial developer. Facing opposition for the move, he cited the need to finance programs for the poor in the face of a $4 million debt. After the archdiocese refused several requests from Groppi to be assigned to an African-American parish, he resigned from the priesthood in 1976. Cousins retired in 1977 after 35 years as archbishop of Milwaukee.

In 1977, Pope Paul VI appointed Reverend Rembert Weakland, abbot primate of the Benedictine Confederation, as archbishop of Milwaukee. One of Weakland's first actions was to sell the suburban home where his predecessor had lived and move to the cathedral rectory. Weakland gave support for the Milwaukee AIDS Project. Amidst abortion controversies, Weakland participated in public "listening sessions", encouraging Catholic women to share their views on the issue.

In early 2002, Weakland submitted his resignation as archbishop to the Vatican. While Weakland was waiting for his resignation to be accepted, the news media in May 2002 reported that the archdiocese had paid a $450,000 settlement in 1998 to Paul Marcoux, a former seminarian. In 1979, Marcoux had told church authorities about his long-term relationship with Weakland. Weakland publicly admitted to the affair after the story broke and apologized during a church service. Later in May, the Vatican accepted Weakland's resignation.

The next archbishop of Milwaukee was Auxiliary Bishop Timothy M. Dolan of St. Louis, named by John Paul II in 2001. Dolan took a special interest in priests and vocations, and the number of seminary enrollments rose during his tenure. In 2009, Dolan was appointed archbishop of New York. To replace Dolan, Pope Benedict XVI named Bishop Jerome E. Listecki of La Crosse in 2009. The archdiocese filed for Chapter 11 bankruptcy protection in January 2011 after it failed to reach a settlement with two dozen victims of sexual abuse by Catholic clergy."

In March 2023, Listecki removed the right to hear confession and give absolution from Reverend James Connell, a retired archdiocesan priest. In an opinion article in USA Today, Connell had expressed support for a proposed Delaware law that would invalidate the clergy-penitent privilege in cases that involved sexual abuse. Listecki accused Connell of spreading false information about the sacrament of confession.

As of 2023, Listecki is the archbishop of the Archdiocese of Milwaukee.

A 2003 report released by the Wisconsin Senate listed 58 priests from the Archdiocese of Milwaukee with credible accusations of sexual abuse of children. In the report, Archbishop Weakland admitted allowing priests guilty of child sex abuse to continue in ministry without warning parishioners or alerting the police. Weakland stated in his 2009 autobiography that in the early years of the sexual abuse scandal, he did not understand that child sexual abuse was a crime.

In July 2011, the archdiocese launched "a national advertising campaign to notify sex abuse victims of their deadline to file claims. As of early 2012, approximately 550 people were asking for restitution for alleged sexual abuse by clergy in the archdiocese. It paid financial settlements to claimants funded "through various sources, including insurance, loans and the sale of property", and funds were set aside to pay for therapy.

In June 2012 it was revealed that Dolan "authorized payments of as much as $20,000 to sexually abusive priests as an incentive for them to agree to dismissal from the priesthood when he was the archbishop of Milwaukee" and that "the archdiocese did make such payments... thereby allowing the church to remove them from the payroll."

In March 2019, the archdiocese announced that it would remove the names of Cousins and Weakland from buildings in the archdiocese due to their poor handling of sex abuse cases. The archdiocese in June 2021 announced that it would only cooperate with an investigation by Wisconsin Attorney General Josh Kaul as far as sexual abuse allegations against living priests. Archbishop Listecki refused to participate in investigations of deceased priests, terming it anti-Catholic bigotry.

As of 2017, the Archdiocese of Milwaukee had a membership of 591,890 Catholics in 198 parishes, representing the most heavily Catholic region of the state. There were 322 diocesan priests, 370 religious priests, and 147 permanent deacons. The religious orders included 82 brothers and 994 women religious.

The archdiocese houses one provincial seminary (St. Francis de Sales Seminary) educating 56 seminarians. It oversees 94 elementary schools, 13 high schools, and five colleges and universities. Also included in the archdiocese are 12 Catholic hospitals and nine Catholic cemeteries.
