Rock Star: INXS is the first season of the reality television show Rock Star where fifteen contestants competed to become the lead vocalist for the Australian rock band INXS.

INXS enjoyed great popularity through the 1980s and early 1990s, but after frontman Michael Hutchence died in 1997, the band attempted to continue with alternate singers, but remained largely dormant until this show. The winner of the series, J. D. Fortune, was announced on Tuesday, September 20, 2005, and became the band's new lead singer. Following the series, on November 29, 2005, the band released the studio album Switch with Fortune on lead vocals.
