The List of the Bishops of Schleswig contains the names of the bishops of the see in Schleswig (, ) in chronological order. Also Lutheran bishops, who officiated after 1542, superintendents and general superintendents are listed.

Note

Between 947 and 948 Archbishop Adaldag of Hamburg-Bremen founded the three suffragan dioceses of , Århus, and Ribe (Ripen). In 1104 the Schleswig see was redeployed in ecclesiastical hierarchy to become a suffragan to the Archdiocese of Lund.

Since 1542 the bishops were Lutherans, partially even lacking theological qualification but only collecting the prebends from the episcopal estates. Therefore, they were assisted by Lutheran (general) superintendents for the pastoral care. Most parishioners adopted Lutheranism too. After 1624 nobody was invested as Bishop of Schleswig any more. General superintendents fulfilled the pastoral functions as to Lutheran faithful. Between 1854 and 1864 the Lutheran church in the Duchy of Schleswig was reorganised as the led again by a cleric titled bishop.

In 1868, two years after the Prussian annexation of Holstein and Schleswig as the Province of Schleswig-Holstein the Lutheran churches in Holstein and Schleswig formed the (Evangelisch-Lutherische Landeskirche Schleswig-Holsteins). By the separation of state and religion after 1918 the privilege of the Prussian monarch as summus episcopus (i.e. supreme governor/bishop of the church) was abolished.

Thus in 1925 Schleswig-Holstein's Lutheran church body assumed the title of bishop, one officiating for the Holstein area, seated in Kiel, and one for Southern Schleswig, seated in Schleswig. The new offices as bishops replaced the prior general superintendents and continued also after the Schleswig-Holstein church body merged with three neighbouring church bodies in the North Elbian Evangelical Lutheran Church in 1977. In 2008 a merger of the offices did away with the office Bishop of Schleswig. Northern Schleswig which returned to Denmark became the Diocese of Haderslev of the Church of Denmark. Their bishop also oversees the Danish Church in Southern Schleswig.

For the very few remaining, immigrating or converted Catholics pastoral functions were provided first by the Vicariate Apostolic of the Northern Missions (as of 1667; reduced by most South-Elbian regions renamed into the Vicariate Apostolic of the North in 1709), and later by the (as of 1868). After 1920 Northern Schleswig became part of the Vicariate Apostolic of Denmark, which transformed into the Roman Catholic Diocese of Copenhagen on 29 April 1953. In Southern Schleswig the rest of the Prefecture Apostolic of Schleswig-Holstein was assigned to the Diocese of Osnabrück in 1929, which had to cede this extension again in favour of the new founded Archdiocese of Hamburg in 1994.
