**Giovanni Amelino-Camelia** (born 14 December 1965, Naples) is an Italian physicist of the University of Naples Federico II who works on quantum gravity.

He is the first proposer of doubly special relativity^{[1]} that is the idea of introducing the Planck length in physics as an observer-independent quantity, obtaining a relativistic theory (like Galileian relativity and Einstein's special relativity). The principles of doubly special relativity probably imply the loss of the notion of classical (Riemannian) spacetime; this led Amelino-Camelia to the study of non-commutative geometry as a feasible theory of quantum spacetime.
Amelino-Camelia is the initiator of "quantum-gravity phenomenology", for being the first^{[2]} to show that with some experiments under reach of current technology sensitivity to Planck-scale effects is feasible (see Fermi Gamma-ray Space Telescope).
