Sandro Donati (Monte Porzio Catone, 14 June 1947) is an Italian athletics coach and antidoping activist.

[2][3] Author of several books about doping, he was Head of Research and Experimentation of Italian National Olympic Committee from 1990 to 2006.

[4] In 1999, after Lance Armstrong's first Tour de France victory, Donati assisted The Sunday Times journalist David Walsh in his pursuit of a connection between Armstrong and the infamous "doping doctor", Michele Ferrari.

Schwzer qualified for the 2016 Summer Olympics, however he never competed as he was found positive to doping for a second time.

Donati believes a conspiracy was enacted to punish him and Schwazer for their whistleblowing against state sponsored doping.
