The Bugis are an Austronesian ethnic group—the most numerous of the three major linguistic and ethnic groups of South Sulawesi, in the southwestern province of Sulawesi, third largest island of Indonesia.

The Austronesian ancestors of the Bugis people settled on Sulawesi around 2500 BCE.

It has been hypothesized that there is "historical linguistic evidence of some late Holocene immigration of Austronesian speakers to South Sulawesi from Taiwan" - which means that the Bugis have "possible ultimate ancestry in South China", and that as a result of this immigration, "there was an infusion of an exogenous population from China or Taiwan." (Susan G. Keates, Juliette M. Pasveer, Quaternary Research in Indonesia. Taylor & Francis, 2004)

The Bugis in 1605 convert to Islam from Animism.

Although many Bugis live in the large port cities of Makassar and Parepare, the majority are farmers who grow wet rice on the lowland plains to the north and west of the town of Maros.

The Bugis speak a distinct regional language in addition to Indonesian, called Basa Ugi, Bugis or Buginese.

In reality, there are several dialects, some of which are sufficiently different from others to be considered separate languages.

Bugis belongs to the South Sulawesi language group; other members include Makasar, Toraja, Mandar and Enrekang, each being a series of dialects.
