Ross Dickran Bagdasarian Jr. (born May 6, 1949) is an Armenian-American actor, singer, animator, and producer, known for his work on the Alvin and the Chipmunks franchise. He is the son of the franchise's creator, Ross Bagdasarian.^[1][2]

Bagdasarian was born in Fresno, California, the son of Armenian-American parents Armenuhi Bagdasarian (née Kulhanjian) and Ross Bagdasarian (1919–1972). As a child, he worked with his father on The Alvin Show by helping edit and coordinate the soundtracks and falsetto voice-overs of the Chipmunks.

Bagdasarian graduated from law school.^[3] He succeeded his father^[3] as president of Bagdasarian Productions in 1972 after the death of the elder Bagdasarian. The company had fallen into obscurity after significant success between 1958 and the late 1960s. Bagdasarian was also admitted to the California bar as an attorney in 1975.^[4]

Under Bagdasarian's supervision, new Chipmunks records were created shortly after his marriage to Karman, including Chipmunk Punk. In 1981, the Chipmunks returned to television in the cartoon special A Chipmunk Christmas. Two years later, Ruby-Spears Productions' Alvin and the Chipmunks Saturday morning cartoon series debuted on NBC. Based on that series, a feature film, The Chipmunk Adventure was released in 1987. Bagdasarian voices Alvin, Simon, and Dave Seville, and Karman voices Theodore and the Chipettes (Brittany, Jeanette, and Eleanor).

Bagdasarian and Karman hold tight creative and financial control over the Chipmunk franchise, reviewing each and every business contract in great detail. In the mid-90s, Bagdasarian bought out his brother's and sister's portions of the Chipmunk rights, to take complete control of the franchise.^[3]

Bagdasarian married Janice Karman in 1980. She is co-president of Bagdasarian Productions.^[6]
