The Heiyin language, also known as the Heigiung language, or simply Hei language, is a variety of Yu spoken in the majority of the Heigiung Autonomous Region of Hondonia and its surrounding areas, as well as the island of Hrastmozh in Kentalis. It is classified as part of the Oriental language family.

Heiyin belongs to the Common Yu subgroup of the Yu languages. With around 1 million speakers, Heiyin is also the largest single form of Yu and used as the standard form of the Yu languages. It used to serve as the lingua franca of the entire western Laurentine bay region, but after the 17th century its status and use declined due to dominating Thuado-Thrismaran languages, which most Heiyin speakers can also speak, and the decline of the Heigiung Kingdom.

Like other Yu varieties, Heiyin has a large number of vowels and consonants, comepared to it's surrounding non-Thuado-Thrismaran languages, with around fifteen unique vowel qualities, six of which are phonemic. Heiyin also has a low number of tones compared to other Oriental languages, and has a system of tone sandhi similar to the Hoterallian pitch accent.
