The Loko (IPA: Lɔkɔ) are one of the indigenous ethnic groups in Sierra Leone.

The majority of the Loko people live in the Northern Province of the country, particularly in Bombali District, and around the capital city of Freetown in communities such as Regent.

Important regional towns include Tambiama, Kalangba, Kagbere, Batkanu, and Gbendembu, though other groups such as the Mandingo, Fula and Temne peoples live there too.

The Loko belong to the larger group of Mande peoples who live throughout West Africa.

The Loko people also utilize practices of the Bondo secret society which aims at gradually but firmly establishing attitudes related to adulthood in girls, discussions on fertility, morality and proper sexual comportment.
