The Peronist, left-wing Frente de Todos ticket of Alberto Fernández, former Chief Cabinet, and Cristina Fernández de Kirchner, National Senator and former president, defeated the center-right Juntos por el Cambio ticket of incumbent president Mauricio Macri and conservative Peronist National Senator Miguel Ángel Pichetto, exceeding the threshold to win the presidency in a single round. Macri became the first incumbent president in Argentine history to be defeated in his reelection bid.

The election of the president was conducted under the ballotage system, a modified version of the two-round system. A candidate can win the presidency in a single round by either winning 45% of the vote, or if they win 40% of the vote while finishing 10 percentage points ahead of the second-place candidate. If no candidate meets either threshold, a runoff takes place between the top two candidates.^[3] Voting is compulsory for citizens between 18 and 70 years old.^[4] Suffrage was also extended to 16- and 17-year-olds, though without compulsory voting.^[5]

There are a total of 257 seats of the Chamber of Deputies. They are elected from 24 electoral districts–the 23 provinces, plus the federal district of Buenos Aires, which elects its own executive and legislature and is represented in the national Congress like all other provinces.^[6] The number of seats are distributed in relation to the population of the province. One-third of the seats in the Chamber of Deputies are reserved for women. The 130 seats of the Chamber of Deputies up for election were elected from 24 multi-member constituencies based on the 23 provinces and Buenos Aires. Seats were allocated using the D'Hondt method of proportional representation, with an electoral threshold of 3%.^[4]

The 24 seats in the Senate up for election were elected in three-seat constituencies using the closed list system. Each district is represented by three senatorial seats. Each party is allowed to register up to two candidates; one of those registered must be female. The party receiving the most votes wins two seats, and the second-placed party wins one.^[7] The third senatorial seat was established in the Constitution of 1994 in order to better represent the largest minority in each district.
