Passerellidae, also known as the New World sparrows.[3]

The genus name Peucaea is from the Ancient Greek word peukē, meaning "pine tree".[7] The species ephithet humeralis is a Late Latin word meaning "of the shoulders" (from the Latin umerus).[8] In the past, the black-chested sparrow was also known as the Ferrari-Perez sparrow.[9]
