Robin Hugh Gibb (22 December 1949 – 20 May 2012) was a British singer and songwriter. He gained worldwide fame as a member of the Bee Gees with elder brother Barry and twin brother Maurice. Robin Gibb also had his own successful solo career. Their youngest brother Andy was also a singer.

Gibb was born at the Jane Crookall Maternity Home, Douglas on the Isle of Man, to English parents, Hugh and Barbara Gibb; the family later moved to Manchester for three years (where Andy was born) before settling in Redcliffe, just north of Brisbane, Australia. Gibb began his career as part of the family trio (Barry-Maurice-Robin). When the group found their first success, they returned to England, where they achieved worldwide fame. In 2002, the Bee Gees were appointed as CBEs for their "contribution to music". However, investiture at Buckingham Palace was delayed until 2004.

With record sales estimated in excess of 200 million, the Bee Gees became one of the most successful pop groups of all time. Music historian Paul Gambaccini described Gibb as "one of the major figures in the history of British music" and "one of the best white soul voices ever" owing to his distinctive vibrato-laden soulful voice. From 2008 to 2011, Gibb was president of the UK-based Heritage Foundation, which honours figures in British culture. After a career spanning six decades, Gibb last performed onstage in February 2012 supporting injured British servicemen at a charity concert at the London Palladium. After numerous health problems in his final years, including a battle with colorectal cancer, Gibb died in May 2012 at the age of 62 from liver and kidney failure.

As a musician, Gibb primarily played a variety of keyboards, notably piano, organ and Mellotron on the Bee Gees album Odessa (1969); he also played acoustic guitar and organ on his debut solo album Robin's Reign (1970).
