List of towns in Romania by ethnic Hungarian population

This list contains Romanian urban localities (municipalities or towns) in which ethnic Hungarians make up over 5% of the total population, according to the 2021 census, ordered by their percentage of the local population. (Note that ethnic data were unavailable for a certain percentage of residents counted during that census, and these were excluded from the total.) The Hungarians are an ethnic group which make up 6% of Romania's population, with nearly all living in Transylvania, where they make up 17.4% of the population.

Hungarians form at least 5% of the population in 73 of Transylvania's 143 towns, accounting for 94.4% of the region's 465,970 urban Hungarians. There are numerous rural localities (communes and villages) which also have Hungarian populations exceeding 5% of the total population, even though those are not listed here. Conversely, Hungarian communities of at least a thousand people, but under the 5% threshold, exist in Timișoara (8313), Bistrița (2898), Hunedoara (1777), Lugoj (1357), Sibiu (1206) and Petroșani (1147), as well as in Bucharest (2168).

In localities where Hungarians make up more than 20% of the population, the Hungarian language can be used when addressing local authorities, while state-funded education and bilingual signs are also provided. This arrangement applies in many communes, as well as in thirty-one cities and towns.
