What is the name of Johnny Cash's only son?

Johnny Cash’s only son was John Carter Cash. Born in 1970, he was the only child of Johnny Cash and his second wife, June Carter Cash.

John Carter Cash grew up inside one of country music’s most influential families. His father was a pioneering singer-songwriter known as the Man in Black, while his mother was a member of the Carter Family and a successful performer in her own right. John’s middle name honors the Carter family connection that shaped both his personal life and musical upbringing.

He became a musician, songwriter, author, and record producer. Much of his career has involved preserving and extending his parents’ musical legacy, including producing recordings connected with the Cash and Carter families. He has also released music of his own, including the album Bitter Harvest.

A common mix-up is confusing “only son” with “only child.” John Carter Cash was Johnny Cash’s only son, but he had four older half-sisters—Rosanne, Kathy, Cindy, and Tara—from Cash’s first marriage to Vivian Liberto. June Carter Cash also had daughters from earlier relationships.
