Edward William Soja (; 1940–2015) was a self-described "urbanist," a noted postmodern political geographer and urban theorist on the planning faculty at UCLA, where he was Distinguished Professor of Urban Planning, and the London School of Economics. He had a Ph.D. from Syracuse University. His early research focused on planning in Kenya, but Soja came to be known as the world's leading spatial theorist with a distinguished career writing on spatial formations and social justice.
