Ekundayo Adeyinka Adeyemi (27 February 1937 – 25 January 2022) was a Nigerian architect and academic who was a distinguished professor of architecture at Covenant University, Ota.
In 1975, Adeyemi attained professorship at Ahmadu Bello University, Zaria a promotion that made him the first professor of architecture in Nigeria and Sub-Saharan Africa.
Ekundayo started his lecturing career at Ahmadu Bello University in 1969, where he rose through the ranks to become the dean of faculty of environmental design in 1976.
In a 2008 study titled Meaning and Relevance in Nigerian Traditional Architecture: The Dialectics of growth and Change, Adeyemi attempted to correct the misconception that Africans dwelled in "unstructured, isolated bush communities with little appreciation of the aesthetics in town design" by providing understandings on what shaped the ancient traditional architectures of buildings across the main ethnic groups in Nigeria, while providing insight and an holistic view on African buildings of old.
The findings from the publication were that the buildings were designed with minimal inputs, ideas and comments from nationals and the mechanism employed has changed over the years from what is being used today.
