Yaul, also known as Ulwa, is a severely endangered Keram language of Papua New Guinea. It is spoken fluently by fewer than 700 people and semi-fluently by around 1,250 people in four villages of the Angoram District of the East Sepik Province: Manu, Maruat, Dimiri, and Yaul.
According to Barlow (2018), speakers in Maruat, Dimiri, and Yaul villages speak similar versions of Ulwa, while those in Manu speak a considerably different version. Thus, he postulates that there are two different dialects of Ulwa.
