The Gullah () are an African American ethnic group who predominantly live in the Lowcountry region of the U.S. states of Georgia, Florida, South Carolina, and North Carolina, within the coastal plain and the Sea Islands. Their language and culture have preserved a significant influence of Africanisms as a result of their historical geographic isolation and the community's relation to their shared history and identity.

Historically, the Gullah region extended from the Cape Fear area on North Carolina's coast south to the vicinity of Jacksonville on Florida's coast. The Gullah people and their language are also called Geechee, which may be derived from the name of the Ogeechee River near Savannah, Georgia. Gullah is a term that was originally used to designate the creole dialect of English spoken by Gullah and Geechee people. Over time, its speakers have used this term to formally refer to their creole language and distinctive ethnic identity as a people. The Georgia communities are distinguished by identifying as either "Freshwater Geechee" or "Saltwater Geechee", depending on whether they live on the mainland or the Sea Islands.

Because of a period of relative isolation from whites while working on large plantations in rural areas, the Africans, enslaved from a variety of Central and West African ethnic groups, developed a creole culture that has preserved much of their African linguistic and cultural heritage from various peoples; in addition, they absorbed new influences from the region. The Gullah people speak an English-based creole language containing many African loanwords and influenced by African languages in grammar and sentence structure. Sometimes referred to as "Sea Island Creole" by linguists and scholars, the Gullah language is sometimes considered as being similar to Bahamian Creole, Barbadian Creole, Guyanese Creole, Belizean Creole, Jamaican Patois and the Sierra Leone Krio language of West Africa. Gullah crafts, farming and fishing traditions, folk beliefs, music, rice-based cuisine and story-telling traditions all exhibit strong influences from Central and West African cultures.
