List of heads of government of Estonia

This is a list of people, who have been heads of government of the Republic of Estonia from 1918, either as a Chairman of the Council of Elders (1918), Prime Minister (1918–1920; 1934–1940 and from 1990), State Elder (1920–1934) or President-Regent (1937–1938). The office of Prime Minister (Peaminister) first came into use soon after Estonia gained its independence in 1918. From 1918 to 1934, Estonia used a parliamentary political system, where the presidency and ministry were subject to parliamentary confidence, but instead of a presidential office, the government was headed by a prime minister and from 1920 to 1934, a similar office called State Elder (Riigivanem).

The 1934 constitution gave the State Elder the role of the president, with a separate head of government created, restoring the office of Prime Minister. The new system was obstructed by a 1934 coup d'état by head of government Konstantin Päts. During his authoritarian era (1934–1937), he ruled as both Prime Minister and State Elder. The latter office was entrusted to him briefly until the presidential elections. In 1937, the two offices were combined into the office of President-Regent (Riigihoidja), but the situation was again changed with the 1938 constitution, when Konstantin Päts gave up the office of Prime Minister to a new officeholder.

The Soviet occupation of Estonia in 1940 made Johannes Vares the new Prime Minister of Estonia, but his rule was later declared to have been illegal. According to the 1938 constitution, Prime Minister was to lead the presidency in case the President couldn't be elected, a move that was implemented for the Estonian Government in Exile. The interim government restored the office of Prime Minister in 1990.
