Hercules and Cacus is a white sculpture to the right of the entrance of the Palazzo Vecchio in the Piazza della Signoria, Florence, Italy. This work by the Florentine artist Baccio Bandinelli (1525–1534) was commissioned as a pendant to David, which had been commissioned by the republican council of Florence, under Piero Soderini (gonfaloniere for life), to commemorate the victory over the Medici.
