Ado Birk, Estonian lawyer and politician, 3rd Prime Minister of Estonia (died 1942)

Ado Birk, was an Estonian politician who was the Estonian Prime Minister for the shortest time.

The prime minister of Estonia is the head of government of the Republic of Estonia. The prime minister is nominated by the president after appropriate consultations with the parliamentary factions and confirmed by the parliament (Riigikogu). In case of disagreement, the parliament can reject the president's nomination and choose their own candidate. In practice, since the prime minister must maintain the confidence of parliament in order to remain in office, he or she is usually the leader of the senior partner in the governing coalition. The current prime minister is Kristen Michal of the Reform Party. He took the office on 23 July 2024 following the resignation of Kaja Kallas.
