Roger Marsh Blench (born August 1, 1953) is a British linguist, ethnomusicologist and development anthropologist.

He has done significant research on the Niger–Congo, Nilo-Saharan, and Afroasiatic families, as well as the Arunachal languages.

Additionally, Blench has published extensively on the relationship between linguistics and archaeology.

Blench is currently engaged in a long-term project to document the languages of central Nigeria.

[5] A series of publications supported by the trust is under way with Rüdiger Köppe Verlag in Cologne.

[8][9] Ethnic groups of Iberia that spoke the Tartessian language may be considered Old North African speakers.

[14] The Libyco-Berber script may be the result of a creolization process between the Berber and Old North African languages; this creolized language may reflect the linguistic connections between modern Berber speakers and Guanche speakers of the Canary Islands.
