The Hungarian diaspora or Magyar diaspora refers to ethnic Hungarians (Magyars) living outside the borders of present-day Hungary. The diaspora can be divided into two main groups.

The first group includes those who are native to their homeland, living in parts of neighbouring regions that were part of Hungary (Kingdom of Hungary) before the Treaty of Trianon.Before entering World War II, Hungary regained some areas, but later lost after the 1947 Treaty of Paris. Following World War I, the Treaty of Trianon in 1920 led to the separation of 32% of ethnic Hungarians, along with many entirely Hungarian-populated regions, from their historical Hungarian motherland. Most of the anti-Hungarian sentiment and incidents still occur today in Hungary's neighboring countries (modern Romania, Serbia, Slovakia, Ukraine), as their predecessor states received large historical Hungarian territories.

The other main group is the emigrants who have left Hungary at various times, and their descendants. Migrations increased during certain pivotal events, notably the Hungarian Revolution of 1956 and the Fall of the Berlin Wall. There has been some emigration since Hungary joined the EU in 2004, especially to countries such as Germany and the United Kingdom, but those patterns have been less extensive than for certain other countries of Central and Eastern Europe, such as Poland and Bulgaria. Additionally, there are the Magyarabs, a small community in Nubia resulting from a historical migration of Magyars, likely during the Ottoman period in Hungary.

Hungarian immigration patterns to Western Europe increased in the 1990s and especially since 2004, after Hungary's admission in the European Union. Thousands of Hungarians from Hungary sought available work through guest-worker contracts in the United Kingdom, Ireland, Finland, Sweden, Spain, and Portugal.

Hungarian citizenship

A proposal supported by the DAHR to grant Hungarian citizenship to Hungarians living in Romania but without meeting Hungarian-law residency requirements was narrowly defeated at a 2004 referendum in Hungary. The referendum was invalid because of not enough participants. After the failure of the 2004 referendum, the leaders of the Hungarian ethnic parties in the neighboring countries formed the HTMSZF organization in January 2005, as an instrument lobbying for preferential treatment in the granting of Hungarian citizenship.

In 2010, some amendments were passed in Hungarian law facilitating an accelerated naturalization process for ethnic Hungarians living abroad; among other changes, the residency-in-Hungary requirement was waived.Mária M.

Hungarian citizens abroad have been able to participate in the parliamentary elections without Hungarian residency starting from the 2014 Hungarian parliamentary election, however, they cannot vote for a candidate running for the seat in a single-seat constituency, but for a party list.
