The president of Armenia is the head of state and the guarantor of independence and territorial integrity of Armenia elected to a single seven-year term by the National Assembly of Armenia. Under Armenia's parliamentary system, the president is simply a figurehead and holds ceremonial duties, with most of the political power vested in the parliament and prime minister.

The prime minister of Armenia is the head of government and most senior minister within the Armenian government, and is required by the constitution to "determine the main directions of policy of the Government, manage the activities of the Government and coordinate the work of the members of the Government." Also, according to the constitution, the prime minister heads the Security Council, which prescribes the main directions of the country's defense policy; thus, the prime minister is effectively the commander-in-chief of the Armed Forces of Armenia. Nikol Pashinyan is the current prime minister. He took the office on 8 May 2018 following the resignation of Serzh Sargsyan.
