Teigne (Serer:Teeñ, alternate spellings include Teñ, Teen, Teign, Tègne, Tin, or Tinou) was the title of the monarchs of the pre-colonial Kingdom of Baol, now part of present-day Senegal.

The title "Teigne" was Serer in origin. Senegalese linquist, author, and professor of linguistic at the Cheikh Anta Diop University, Professor Souleymane Faye notes that, the Serer term "foɗeen", which means "milk from the mother's breast", contains the radical "ɗeen", an altered form of "teen" which means "the breast". This refers to the mother and the matrilineage.

The Wolof folk etymology that Teigne mean "support placed on the head" or any article to be placed on the head, is based on patriarchy and somewhat recent, and does not tally with the historical mood of succession in Baol before the Faal family came on the throne—who changed the mood of succession from matrlineality to patrilineality. Teigne refers to matrilineage, through the mother's milk, and not articles that goes on the head. "Tange" is one of the many spelling variations of teigne, teen, or teeñ, and refers to the mother's milk (matrilineage) derived from the Serer word ɗeen, sometimes spelled ƭeen or den. This is the root of the Serer term ƭeen yaay or den yaay which means maternal inheritance or matrilineage.

The first Teignes of Baol were members of the Soninke Wagadou (or Ouagadou) matrilineage had ruled much of the Senegambia region, and included members of the Serer Joof paternal line, such as Boureh Joof (or Bouré Diouf in French speaking Senegal) and Guidiane Joof (probably "Jegan" Joof). The alliance between the Wagadou and the local Serers was similar to the later arrangement between the Serer and Guelowar matrilineage who largely supplanted the Wagadou in the 14th century.

The last Serer king of Baol was Teigne Niokhor Njie (or Teeñ Niokhor Ndiaye), son of Lingeer Sobel Joof, a descendant of Maad Ndaah Njemeh Joof. After his death, he was succeeded by his maternal nephew Amary Ngone Sobel Fall, a member of the Faal royal family of Cayor and Baol but Wagadou as well. After the death of Teigne Niokhor Njie, the Serers completely lost power in Baol.

The Faal dynasty (or Fall in French), like many of their predecessors, were of Serer origin on the paternal side and Wagadou (Soninke) on the maternal side, but became Wolofized, and saw themselves as Wolofs.

The Kingdom of Baol was part of the Jolof Empire beginning in the 14th century. In 1549, the then-Prince of Cayor Amary Ngone Sobel Fall, assisted by his cousin Prince Manguinak Joof of Baol, launched a rebellion against the Emperor in order to attain independence for their countries. That rebellion culminated in the Battle of Danki in which the Cayor–Baol alliance was victorious. Amary Ngoneh made his cousin Manguinak Jaraaf Baol (equivalent of Prime Minister), and became the first Damel-Teigne, ruler of both states. This arrangement did not last, but many later rulers, including Lat Sukaabe Fall and Lat Dior, also attempted to unite the two kingdoms in a personal union.

The last Teigne of Baol was Tanor Ngone Jeng (or Tanor Goñ Dieng), who reigned from 1890 to 3 July 1894.
