The Armenian Prime Minister Andranik Margaryan dies of a heart attack.
- Hovik Abrahamyan resigns as Prime Minister of Armenia citing civil unrest and a sharp economic downturn.
- Armenian Prime Minister Serzh Sargsyan is elected as President in a contest hailed as largely democratic by OSCE and international monitors.
- Authorities declare that the Republican Party, led by President Serzh Sargsyan, wins the Armenia election amid accusations by opposition parties and the Organization for Security and Co-operation in Europe of voting irregularities.
- Voters in Armenia go to the polls for an election, the first since constitutional changes were approved in a referendum in 2015, which changed the country's governance from a semi-presidential system to a parliamentary republic. Opinion polls predict a tight race between the nationalist Republican Party, led by President Serzh Sargsyan, and the centre-right Prosperous Armenia, led by Gagik Tsarukyan. With votes from 64% of the polling stations counted, the Republican Party leads with 49.7% of votes.
- Armenia and the European Union agree on a new pact to boost ties between the two. It is expected to be signed later this year. This comes after Armenia rejected an Association Agreement in 2013.
