The Luhya (also known as Avaluhya, Abaluhya, or Luyia) are a Bantu ethnic group in Kenya. They also live in Uganda and Tanzania albeit a minor populace. They number about 6.1 million people, being about 16% of Kenya's total population of 38.5 million.

Luhya refers to both the people and their language. There are 18 (and by other accounts, 19, when the Suba are included) tribes that make up the Luhya. Each with a distinct dialect. The word Luhya or Luyia in some of the dialects means "clan", and Abaluhya thus means "people of the clan". Other translations are "those of the same hearth."

The sixteen tribes are the Bukusu (Ava-Bukusu), Idakho (Av-Idakho), Isukha (Av-Isukha), Kabras (Ava-Kabras), Khayo (Ava-Khayo), Kisa (Aba-Kisa), Marachi (Ava-Marachi), Maragoli (Ava-Logoli), Marama (Aba-Marama), Nyala (Ava-Nyala), Nyole (Ava-Nyole), Samia (Ava-Samia), Tachoni (Ava-Tachoni), Tiriki (Ava-Tiriki), Tsotso (Ava-Tsotso), Wanga (Aba-Wanga). They are closely related to the Masaba (or Gisu), whose language is mutually intelligible with Luhya. The Bukusu and the Maragoli are the two largest Luhya tribes.
