The Biloxi tribe are Native Americans of the Siouan-language family.

They call themselves by the autonym Tanêks(a) in Siouan Biloxi language.

When first encountered by Europeans in 1699, the Biloxi inhabit an area near the coast of the Gulf of Mexico near what is now the city of Biloxi, Mississippi.

They are eventually forced west into Louisiana and eastern Texas.

The Biloxi language--Tanêksąyaa ade--has been extinct since the 1930s, when the last known native semi-speaker, Emma Jackson, died.Today, remaining Biloxi descendants have merged with the Tunica and other remnant peoples.

They were federally recognized in 1981 as the Tunica-Biloxi Tribe of Louisiana and share a small reservation.

The two main tribes were from different language group.

Today the tribe members speak English or French.
