Romanian Catholics, like Catholics elsewhere, are members of the Catholic Church under the spiritual leadership of the Pope in Rome. The administration for the local Latin Church is centered in Bucharest, and comprises two archdioceses and four other dioceses. It is the second largest Romanian denomination after the Romanian Orthodox Church, and one of the 18 state-recognized religions. The 2022 census indicated that there were 741,504 Romanian citizens adhering to the Latin Church (3.89% of the population). Of these, the largest groups were Hungarians (54.7% or 405,212, including Székely and Csángó), Romanians (38.2% or 283,092), Germans (1.7% or 12,495) and Slovaks (0.9% or 6,853).

Most Romanian Latin Catholics inhabit the region of Transylvania and Bacău County in Moldavia. Smaller Latin Catholic communities exist among Banat Bulgarians, Italian-Romanians, Polish-Romanians, Croat-Romanians and Krashovani, Czech-Romanians and the local Romani people.

The Hungarian National Council of Transylvania (Hungarian: Erdélyi Magyar Nemzeti Tanács, EMNT; Romanian: Consiliul Național al Maghiarilor din Transilvania, CNMT) is a civic organization that represents the ethnic Hungarians of Romania. Established in 2003, its chairman is László Tőkés. The organisation intends to present, represent and move the case of Hungarian autonomy in Transylvania.

In 2009, the coalition between UDMR and Hungarian National Council of Transylvania resulted in nine percent of the votes in the European Parliamentary elections which meant three Romanian EP seats.
