The Uralic languages (/jʊəˈrælɪk/ yoor-AL-ik), sometimes called the Uralian languages (/jʊəˈreɪliən/ yoor-AY-lee-ən), are spoken predominantly in Europe and North Asia. The Uralic languages with the most native speakers are Hungarian, Finnish, and Estonian. Other languages with speakers above 100,000 are Erzya, Moksha, Mari, Udmurt and Komi spoken in the European parts of the Russian Federation. Still smaller minority languages are Sámi languages of the northern Fennoscandia; other members of the Finnic languages, ranging from Livonian in northern Latvia to Karelian in northwesternmost Russia; the Samoyedic languages and the other members of the Ugric languages, Mansi and Khanty spoken in Western Siberia.

The name Uralic derives from the family's purported "original homeland" (Urheimat) hypothesized to have been somewhere in the vicinity of the Ural Mountains, and was first proposed by Julius Klaproth in Asia Polyglotta (1823).

Finno-Ugric is sometimes used as a synonym for Uralic but more accurately refers to a disputed subdivision of the Uralic languages which excludes the Samoyedic languages. Scholars who do not accept the traditional notion that Samoyedic split first from the rest of the Uralic family may treat the terms as synonymous.

Uralic languages are known for their often complex case systems and vowel harmony.

Proposed homelands of the Proto-Uralic language include:

The first plausible mention of a people speaking a Uralic language is in Tacitus's Germania (c. 98 AD), mentioning the Fenni (usually interpreted as referring to the Sámi) and two other possibly Uralic tribes living in the farthest reaches of Scandinavia. There are many possible earlier mentions, including the Iyrcae (perhaps related to Yugra) described by Herodotus living in what is now European Russia, and the Budini, described by Herodotus as notably red-haired (a characteristic feature of the Udmurts) and living in northeast Ukraine and/or adjacent parts of Russia. In the late 15th century, European scholars noted the resemblance of the names Hungaria and Yugria, the names of settlements east of the Ural. They assumed a connection but did not seek linguistic evidence.

The affinity of Hungarian and Finnish was first proposed in the late 17th century. Three candidates can be credited for the discovery: the German scholar Martin Fogel [de], the Swedish scholar Georg Stiernhielm, and the Swedish courtier Bengt Skytte. Fogel's unpublished study of the relationship, commissioned by Cosimo III of Tuscany, was clearly the most modern of these: he established several grammatical and lexical parallels between Finnish and Hungarian as well as Sámi. Stiernhielm commented on the similarities of Sámi, Estonian, and Finnish, and also on a few similar words between Finnish and Hungarian. These authors were the first to outline what was to become the classification of the Finno-Ugric, and later Uralic family. This proposal received some of its initial impetus from the fact that these languages, unlike most of the other languages spoken in Europe, are not part of what is now known as the Indo-European family. In 1717, the Swedish professor Olof Rudbeck proposed about 100 etymologies connecting Finnish and Hungarian, of which about 40 are still considered valid. Several early reports comparing Finnish or Hungarian with Mordvin, Mari or Khanty were additionally collected by Gottfried Leibniz and edited by his assistant Johann Georg von Eckhart.

In 1730, Philip Johan von Strahlenberg published his book Das Nord- und Ostliche Theil von Europa und Asia (The Northern and Eastern Parts of Europe and Asia), surveying the geography, peoples and languages of Russia. All the main groups of the Uralic languages were already identified here. Nonetheless, these relationships were not widely accepted. Hungarian intellectuals especially were not interested in the theory and preferred to assume connections with Turkic tribes, an attitude characterized by Merritt Ruhlen as due to "the wild unfettered Romanticism of the epoch". Still, in spite of this hostile climate, the Hungarian Jesuit János Sajnovics traveled with Maximilian Hell to survey the alleged relationship between Hungarian and Sámi, while they were also on a mission to observe the 1769 Venus transit. Sajnovics published his results in 1770, arguing for a relationship based on several grammatical features. In 1799, the Hungarian Sámuel Gyarmathi published the most complete work on Finno-Ugric to that date.
