Dukagjin (Albanian definite form: Dukagjini) is a village in the former municipality of Malzi in Kukës County, Albania. At the 2015 local government reform it became part of the municipality Kukës.

The name of the village is derived from the Albanian noble family of the Dukagjini from the Middle Ages, which ruled the area before the Ottoman invasion.

Unlike many other villages in the area, Dukagjin is not mentioned in any of the three Ottoman defters in the 16th century. It was first mentioned in 1638 by Frang Bardhi, with its present name. He notes: "The second village is Dukagjin, consisting of 15 houses and 100 inhabitants, which also has the earlier mentioned Church of St. Sebastian as its church."

The village is mentioned again in the works of Vicko Zmajević in 1703, Ivan Jastrebov in 1904, and the Austro-Hungarian census of 1916–18.

In the late 19th century, Albanologist Theodor Ippen noted that the imam of Dukagjin still preserved the decorations from the altar of the former Catholic Church. A similar observation was made by Jastrebov in 1904, who wrote that a local resident had informed him of an imam in Dukagjin who was said to be descended from the village's Catholic priests. This imam reportedly kept items belonging to the priests in his home. Furthermore, the current mosque is believed to have been constructed on the ruins of the old church.

In 1923, the first Albanian-language school in the area of Malzi was opened in Dukagjin.
