In January 2015, the National Electoral Committee announced that ten political parties and eleven individual candidates had registered to take part in the 2015 parliamentary election. Individuals from contesting political parties also participated in multiple organised debates in January and February 2015.

Following this election, Reform successfully negotiated with the Triple Alliance parties SDE and IRL afterwards, forming a second government headed by Rõivas in April. This coalition fell after a vote of confidence in the following year, bringing about the first government to not feature Reform since 1999 due to the collapse of the cordon sanitaire around the Centre Party after it elected a new leader, ending the long-lasting leadership of Edgar Savisaar, who had been perceived as too Russophilic.^[2][3]

This was the first election since the resignation of Prime Minister Andrus Ansip, who relinquished his position after holding the office for almost nine years, a record-length tenure for an Estonian head of government. Following the resignation, a new coalition comprising the Estonian Reform Party and the Estonian Social Democrats were authorized to form a new government on 24 March 2014 with 34-year-old Taavi Rõivas as the new Prime Minister. This replaced the prior coalition of the Estonian Reform Party and the Pro Patria and Res Publica Union.^[4]

The 101 members of the Riigikogu were elected by proportional representation in twelve multi-member constituencies. The seats were allocated using a modified D'Hondt method. Parties had to pass a nationwide threshold of 5%, but if the number of votes cast for an individual candidate exceeded or equalled the simple quota (obtained by dividing the number of valid votes cast in the electoral district by the number of mandates in the district), they were elected.

The Estonian National Electoral Committee announced that ten political parties and 11 individual candidates registered to take part in the 2015 parliamentary election. Their registration numbers and order were determined by a draw lot.

Poll results are listed in the table below in reverse chronological order, showing the most recent first. The highest percentage figure in each poll is displayed in bold, and the background shaded in the leading party's color. In the instance that there is a tie, then no figure is shaded.

The Reform Party started coalition talks with the Social Democrats, Pro Patria and Res Publica Union (IRL) and the Free Party.^[6] After nearly three weeks of negotiations, the Free Party left the coalition talks due to disagreements with the Reform Party and the IRL.^[7] The three remaining parties signed the coalition treaty on 8 April, and the cabinet took office on 9 April.^[8]
