Nipper, also known as the RCA Victor dog, was a dog from Bristol, England. Bred as a terrier mix, he served as the model for a 1898 painting by British painter Francis Barraud titled His Master's Voice. This image became one of the world's best known trademarks, the famous dog-and-gramophone pairing that was used by several record companies and their associated company brands, including Berliner Gramophone and its various affiliates and successors, among them Berliner's German subsidiary Deutsche Grammophon; Berliner's American successor the Victor Talking Machine Co. ; Zonophone; Berliner's British affiliate the Gramophone Co. Ltd. and its successors EMI and HMV Retail Ltd.; the Gramophone Co.'s German subsidiary Electrola; and onetime Victor subsidiary the Japan Victor Company (JVC).

Francis James Barraud was an English painter. He is best known for his work His Master's Voice, one of the most famous commercial logos in the world, having inspired a music industry trademark used by corporations including EMI, HMV, RCA Victor and JVC. The image, which depicts a dog named Nipper, ear cocked as he listens to a wind-up disc gramophone helped popularize the nascent field of sound recording and brought Barraud worldwide fame. He subsequently established himself as an artist for corporate clients, spending the rest of his career producing at least two dozen copies of the painting which made his name.
