Hungarians, also known as Magyars ( MAG-yarz; Hungarian: magyarok [ˈmɒɟɒrok]), are a nation and ethnic group native to Hungary (Hungarian: Magyarország) and historical Hungarian lands who share a common culture, history, ancestry and language. The Hungarian language belongs to the Uralic language family. There are an estimated 14.2–14.5 million ethnic Hungarians and their descendants worldwide, of whom 9.6 million live in today's Hungary (as of 2016). About 2.2 million Hungarians live in areas that were part of the Kingdom of Hungary before the Treaty of Trianon in 1920 and are now parts of Hungary's seven neighbouring countries, Slovakia, Ukraine, Romania, Serbia, Croatia, Slovenia, and Austria. Significant groups of people with Hungarian ancestry live in various other parts of the world, most of them in the United States, Canada, Germany, France, the United Kingdom, Chile, Brazil, Australia and Argentina.

Hungarians can be divided into several subgroups according to local linguistic and cultural characteristics; subgroups with distinct identities include the Székelys, the Csángós, the Palóc and the Matyó. The Jász people are considered to be an originally Iranic ethnic group more closely related to the Ossetians than to other Hungarians.
