The coat of arms of Pichilemu (Spanish: Escudo de armas de Pichilemu) is the official heraldic symbol representing the city of Pichilemu, the capital of the Chilean province of Cardenal Caro. It consists of a party per cross referencing the importance of tourism in Pichilemu, and the commune's agricultural, huaso origins. The coat of arms is crested with a "symbolical representation of Pichilemu's past and present: a balustrade fused in a mitre", worn by José María Caro Rodríguez, the first Cardinal of the Chilean Roman Catholic Church, who was born in the village of San Antonio de Petrel, in Pichilemu.
