The Segeju (Swahili: Wasegeju; Mijikenda: Asagidzu) are a Bantu ethnolinguistic group mostly based in Tanzania's Tanga Region (particularly Mkinga District) and Kenya's Kwale County.

Segeju migration to urban areas often results in severance of community ties, leading to a lack of transmission of important cultural traditions and language.

The Segeju were said to have acquired the name following contact with the Shirazis in the 17th century, on account of the habit of their wearing of skin garments around their loins higher than was usual.

[7] Segeju oral traditions describe a close historical connection between them and the Dhaiso, an ethnic group primarily inhabiting the foot of the Usambara Mountains.

Shortly afterward the Segeju occupied Mombasa, eventually surrendering it to the Sheikh of Malindi, who invites his ally, the Portuguese, to set up base.

][citation needed] Virtually all Segeju are Sunni Muslims of the Shafi'ite school of thought due to a series of historical interactions and intermarriages with the neighboring Vumba Swahili in the 17th century.
