Jimmy Barnes (b. 1956) is an Australian rock singer.

Barnes was born James Dixon Swan on the 28th April 1956 in Glasgow, Scotland, and moved to Australia with his family when he was six years old.

He first came to public attention as the lead singer with popular Australian pub-rock band Cold Chisel, which he joined in 1973 and with whom he recorded seven albums between 1978 and 1983. When the band split up in 1983 he launched a solo career almost immediately; his first album, Bodyswerve, entered the Australian charts at number one.
