[3] The 2016 election was a surprise landslide victory for the Lithuanian Farmers and Greens Union (LVŽS), which won 54 seats, including half of the single-member constituencies.

After the 2019 presidential election, Order and Justice and the Electoral Action of Poles in Lithuania – Christian Families Alliance joined a coalition.

[7] In the second round special polling places for self-isolating voters were set up in Vilnius, Kaunas, Šiauliai and Raseiniai districts.

[8] On 21 October, a few days before the second round, Lithuanian municipalities were divided into green, yellow and red "risk zones", with de facto lockdown rules, mask mandates and limits on capacities.

All parties involved in the pre-election coalition, including the Lithuanian Farmers and Greens Union, Social Democratic Labour Party, and Electoral Action of Poles in Lithuania – Christian Families Alliance, lost seats compared to what they held prior, with the Farmers and Greens losing over 40% of their prior seats.

The Electoral Action of Poles also failed to make the 5% threshold for national list seats for the first time since 2008 (although the party's support was declining ever since 2014 European Parliament election).

The Labour Party saw a rebound at the national level from its disappointing performance in 2016, gaining 8 seats overall and obtaining nearly 10% of the popular vote.

Overall, the Homeland Union – Lithuanian Christian Democrats, the Liberal Movement and the Freedom Party got most support from the cities.

On 15 October, four days after the first round, the leaders of the Homeland Union – Lithuanian Christian Democrats, the Liberal Movement, and the Freedom Party published a joint declaration, which stated that all three parties nominate Ingrida Šimonytė as their joint candidate to be Prime Minister of Lithuania.

Unlike during the rest of the year, the official numbers of cases and deaths rose exponentially in November and December (see COVID-19 effects).
