The Megleno-Romanians, also known as Meglenites, Moglenite Vlachs or simply Vlachs, are an Eastern Romance ethnic group, originally inhabiting seven villages in the Moglena region spanning the Pella and Kilkis regional units of Central Macedonia, Greece, and one village, Huma, across the border in North Macedonia. These people live in an area of approximately 300 km2 in size. Unlike the Aromanians, the other Romance-speaking population in the same historic region, the Megleno-Romanians are traditionally sedentary agriculturalists, and not traditionally transhumants. Sometimes, the Megleno-Romanians are referred as "Macedo-Romanians" together with the Aromanians.

Megleno-Romanian is an Eastern Romance language, similar to Aromanian. It is spoken by the Megleno-Romanians in a few villages in the Moglena region that spans the border between the Greek region of Macedonia and North Macedonia. It is also spoken by emigrants from these villages and their descendants in Romania, in Turkey by a small Muslim group, and in Serbia. It is considered an endangered language.
