Riccardo Rattazzi (born 1964) is an Italian theoretical physicist and a professor at the École Polytechnique Fédérale de Lausanne. His main research interests are in physics beyond the Standard Model and in cosmology.

Riccardo Rattazzi studied physics at the Scuola Normale Superiore di Pisa and at the University of Pisa, where he received the Laurea cum laude in 1987. He carried out graduate research at the Scuola Normale Superiore di Pisa under the guidance of Riccardo Barbieri. He held postdoctoral positions at the University of California, Berkeley (1992-1993), at the Rutgers University (1993-1996), and at CERN (1996-1998). In 1998 he became a permanent researcher at the Instituto Nazionale di Fisica Nucleare in Pisa. From 2001 to 2006 he was a junior staff member of the theoretical physics department at CERN. Since 2006 he holds a professorship of physics at the École Polytechnique Fédérale de Lausanne.

In 1998, together with Gian Giudice, Markus Luty and Hitoshi Murayama, Riccardo Rattazzi discovered the anomaly mediated supersymmetry breaking, a subtle quantum mechanical mechanism which contributes to the gaugino masses in supergravity.

In 1999, together with Gian Giudice and James Wells, Riccardo Rattazzi carried out the first detailed study of the collider signatures of the large extra dimension scenarios of TeV-scale gravity.
