Moldovans, sometimes referred to as Moldavians (Romanian: moldoveni, Moldovan Cyrillic: молдовень, pronounced [moldoˈvenʲ]), are an ethnic group native to Moldova, who mostly speak the Romanian language, also referred to locally as Moldovan. Moldovans form significant communities in Romania, Italy, Ukraine and Russia.

There is an ongoing controversy in Moldova over whether Moldovans constitute an ethnic group separate from Romanians or not. 77.18% and 7.9% of the Moldovan population declared Moldovan and Romanian ethnicity respectively in the 2024 Moldovan census, with 49.2% declaring their mother language to be Moldovan and 31.3% declaring it to be Romanian. According to opinion polls, around one third of Moldova's population supports unification with Romania.^{[neutrality is disputed][improper synthesis?]}

The term "Moldavian" can also be used to refer to the inhabitants of the territory of the historical Principality of Moldavia, currently divided among Romania (47.5%), Moldova (30.5%) and Ukraine (22%). In Romania, natives of Western Moldavia identifying with the term declare Romanian ethnicity, while the natives of the Republic of Moldova are usually called "Bessarabians" (Romanian: basarabeni).

According to Miron Costin, a prominent chronicler from 17th-century Moldavia, the inhabitants of the Principality of Moldavia spoke Latin and called themselves "Moldavians", but also "Romans" (with the local form "român/râmlean") which, he notes, comes from "romanus". Also, the Slavic neighbours called Moldovans "Vlachs" or "Volokhs", a term also used to refer to all native Romance speakers from Eastern Europe and the Balkan peninsula.

In 1812, the Russian Empire received the eastern half of Moldavia from the Ottoman Empire and named it Bessarabia. As the ethnonym "Romanian" was gaining more and more popularity throughout the remaining territory of Moldavia and Bukovina during the 19th century, its dissemination in Bessarabia, a more backward and rural province of the Russian Empire at the time, was welcomed mostly by the Romanian-oriented intellectuals, while the majority of the rural population continued to use the old self-identification "Moldovans".

Some authors observe that the Russian officials also initially preferred to refer to the native inhabitants of Bessarabia as "Romanians" (or "Volochi"), but after the 1859 unification of Moldavia and Wallachia they gradually began using the term "Moldavians" for them, to justify the idea of Russifiers and Pan-Slavists to create an identity different from that of the Romanians of Western Moldavia. Historian van Meurs however indicates that some Russian official documents and scholarly studies in the 19th century actually continued to use both "Romanians" and "Moldavians" when referring to the local population, noting that the Russian policy which restricted the use of the Romanian language in Bessarabia was rather part of the general tendency of Russification and of promotion of a tsarist nationality policy as such.

Van Meurs concludes that before the October Revolution the inhabitants of Bessarabia probably considered themselves "Moldavians" in a "natural, primarily local-territorial sense", and there had been no consistent government-sponsored effort to influence the local nation-building process by promoting a Moldavian identity. Likewise, historian Charles King notes that the Moldovan peasant's view of his own national identity was not the product of Russian assimilationist policies but had instead remained virtually frozen since 1812. The Romanian researcher Irina Livezeanu further notes that the Russification policies did not greatly affect the identity of the Moldavians, as their overwhelming majority were illiterate peasants.

Until the 1920s, Romanian historians generally considered Moldovans as a subgroup of the Romanian ethnos. After 1924, within the newly created Moldavian Autonomous Soviet Socialist Republic, Soviet authorities supported the creation of the Moldovan language standards allegedly in order to prove that Moldovans form a separate ethnic group.
