Shahab Ahmed (Urdu: شہاب احمد; December 11, 1966 – September 17, 2015) was a Pakistani scholar of Islam at Harvard University.
Ahmed's posthumous work What Is Islam? was listed in The Chronicle of Higher Education as one of the eleven best scholarly books of the 2010s, chosen by Noah Feldman. Professor Elias Muhanna of Brown University described the work as "a strange and brilliant work, encyclopedic in vision and tautly argued in the manner of logical proof, yet pervaded by the urgency of a political manifesto".
