Thrasybulus (; 'brave-willed'; died 388 BC) was an Athenian general and democratic leader. In 411 BC, in the wake of an oligarchic coup at Athens, the pro-democracy sailors at Samos elected him as a general, making him a primary leader of the successful democratic resistance to that coup. As general, he was responsible for recalling the controversial nobleman Alcibiades from exile, and the two worked together extensively over the next several years. In 411 and 410, Thrasybulus commanded along with Alcibiades and others at several critical Athenian naval victories.
