Vinhais (European Portuguese: [viˈɲajʃ] ⓘ; Proto-Celtic: *Veniatia) is a municipality in the district of Bragança, northern Portugal.

This ancient town, older than the founding of Portugal, owes its name to the abundance of vineyards that covered the slopes and produced excellent wine.

One of the first kings of Portugal, Sancho II had a castle and walls built, around which grew a small town soon to be called Vinhaes.

Without industry and with a diminishing population, it relies on tourism, an annual fair specializing in smoked meats, and some agriculture, especially chestnut growing.

To accomplish a better understanding of the wild life, there is now a Biological Park (Parque Biológico de Vinhais) in the Ciradelha Mountain.
