The Temne are a West African ethnic group. They are predominantly found in the Northern Province of Sierra Leone. Some Temne are also found in Guinea. The Temne constitute one of the largest ethnic groups in Sierra Leone, at 35.5% of the total population, which is slightly bigger than the Mende people at 31.2%. They speak Temne, a Mel branch of the Niger–Congo languages.

The Temne people migrated from the Futa Jallon region of Guinea, who left their original settlements to escape Fula jihads in the 15th century and migrated south before settling between the Kolenté and Rokel River area of Sierra Leone. They initially practiced their traditional religion before Islam was adopted through contact with Muslim traders from neighboring ethnic groups. Though most Temne converted to Islam over time, some have continued with their traditional religion.
