It was an apostolic administration (quasi-diocesan jurisdiction) of the Latin Roman Catholic Church in Estonia from its formation in 1924 to 2024.

In 1918, when Estonia gained independence, its citizens had complete freedom of religion.

The Apostolic Administration of Estonia was established on November 1, 1924,[1] on territory split off from the Roman Catholic Archdiocese of Riga (in the neighboring Baltic country Latvia).

The see remained vacant during most of the period when Estonia was occupied and annexed into the USSR after the death of Bishop Eduard Profittlich in 1942 because of the suppression of the Church by Soviet communist authorities.

It enjoyed a papal visit in September 1993 from Pope John Paul II.
