The Roman Catholic diocese was established in place of the local Greek Orthodox see following the conquest of the islands by the Fourth Crusade in the early 1200s. It was renamed in 1400 to the Diocese of Tinos and Mykonos (Latin: Tinensis et Myconensis), including the island Mykonos in its title.

In 1824 it gained territory from the suppressed Roman Catholic Diocese of Andros, but did not change its name to include this title.

The diocese was finally suppressed on 3 June 1919, when its territory and titles, even that of Andros, were included in the newly renamed Roman Catholic Archdiocese of Naxos, Andros, Tinos and Mykonos (formerly the Archdiocese of Naxos).
