Parliamentary elections were held in Hungary on 3 April 2022 to elect the National Assembly, coinciding with a referendum. Hungary's incumbent prime minister Viktor Orbán won re-election to a fourth term. Addressing his supporters after the partial results showed Fidesz leading by a wide margin, Orbán said: "We won a victory so big that you can see it from the moon, and you can certainly see it from Brussels." Opposition leader Péter Márki-Zay admitted defeat shortly after Orbán's speech. Reuters described it as a "crushing victory".

The National Assembly is the parliament of Hungary. The unicameral body consists of 199 members elected to four-year terms. Election of members is done using a semi-proportional representation: a mixed-member majoritarian representation with partial compensation via transfer votes and mixed single vote; involving single-member districts and one list vote; parties must win at least 5% of the popular vote in order to gain list seats. The Assembly includes 25 standing committees to debate and report on introduced bills and to supervise the activities of the ministers. The Constitutional Court of Hungary has the right to challenge legislation on the grounds of constitutionality.
