The Kenyah languages are a group of half a dozen or so closely related languages spoken by the Kenyah peoples of Borneo. They are:
Ethnologue says that the Punan–Nibong languages are related to Uma’ Lasan, Glottolog that they are outside the Kenyah languages.

Classification

Soriente proposes a Kayan-Kenyah grouping.

Proto–Kayan-Kenyah
*Kenyah
**Upper Pujungan
**Usun Apau
*Penan
**West Penan
**East Penan
*Kayanic
**Lebu Kulit
**Mboh
**Ngorek
**Kayan

However, Smith rejects Soriente's grouping, and argues that Kenyah and Kayan are separate groups. Smith proposes the following classification.

Proto-Kenyah
*Highland
**Highland A dialects: Lepo Gah, Lepo Sawa, Lepo Laang, Lepo Baha, Lepo Maut, Lepo Ké, Bakung, Lepo Ndang
**Highland B dialects: Lepo Tau, Badeng, Uma Lasan, Uma Alim, Òma Lóngh
*Lowland
**Western Lowland dialects: Lebo' Vo'
**Eastern Lowland dialects: Lebu Kulit, Lebuq Timai, Uma Pawa, Uma Ujok, Uma Kelap/Kelep
*Penan-Sebop
**Penan
**Sebop

This classification of Kenyah languages was updated in a second publication, "Penan, Sebop, and Kenyah internal classification". There, it was shown that Penan and Sebop subgroup specifically with the Western-Lowland branch of Lowland Kenyah. This subgrouping was repeated in the dissertation, "The languages of Borneo: a comprehensive classification".

Proto-Kenyah
*Highland
**Highland A dialects: Lepo Gah, Lepo Sawa, Lepo Laang, Lepo Baha, Lepo Maut, Lepo Ké, Bakung, Lepo Ndang
**Highland B dialects: Lepo Tau, Badeng, Uma Lasan, Uma Alim, Òma Lóngh
*Lowland
**Western Lowland dialects: Lebo' Vo', Eastern Penan, Western Penan, Sebop
**Eastern Lowland dialects: Lebu Kulit, Lebuq Timai, Uma Pawa, Uma Ujok, Uma Kelap/Kelep
