John Philip Jacob Elkann (born 1 April 1976) is an American-born Italian industrialist. In 1997, he became the chosen heir of his maternal grandfather Gianni Agnelli, following the death of Gianni's nephew Giovanni Alberto Agnelli, and since 2004 has been leading the Agnelli family, an Italian multi-industry business dynasty. The Agnelli family has been described in media as comparable to the Kennedy family in terms of prominence in national affairs.
