The Diocese of Tallinn is a Latin Church diocese that covers the entire country of Estonia.

It was an apostolic administration (quasi-diocesan jurisdiction) of the Latin Roman Catholic Church in Estonia from its formation in 1924 to 2024. Its cathedral episcopal see, the St. Peter and St. Paul's Cathedral, is located in Tallinn.

The post of apostolic administrator was often held by titular archbishops who also held posts in the diplomatic service of the Holy See as nuncio to Estonia, Latvia, and Lithuania.
