Early parliamentary elections were held in the Slovak Republic on 30 September 2023 to elect members of the National Council. Regular elections were scheduled to be held in 2024. However, on 15 December 2022 the government lost a no-confidence vote. Subsequently, the National Council amended the Constitution so that an early election could be held on 30 September 2023. This was the first snap election in the country since 2012.

The National Council of the Slovak Republic is the national parliament of Slovakia. It is unicameral and consists of 150 members, who are elected by universal suffrage under proportional representation with seats distributed via largest remainder method with Hagenbach-Bischoff quota every four years.
