Colin Frederick Jacobsen AM (born 13 April 1936 in Sydney, New South Wales), better known as Col Joye, is an Australian popular entertainer and entrepreneur. He was the second Australian rock and roll singer after Johnny O'Keefe to have a number one record in Australia and the first Australian to reach the American Billboard charts, with "Bye Bye Baby", "Stagger Lee" and "Oh Yeah Uh Huh" in 1959.

Recording with his brothers Kevin and Keith (who were part of Col's backing band The Joy Boys), and as a solo artist, Col Joye enjoyed a series of number one hits in the early 1960s in Australia. He was an original member of Brian Henderson's Bandstand television program and appeared regularly for fourteen years. After the Beatles took music by storm, Col Joye's popularity leveled off, and it was not until 1973 that he had another hit record, "Heaven Is My Woman's Love".

In the interim, Col and Kevin built an influential entertainment management, publishing, and recording business, including ATA Studios in Glebe, New South Wales and they worked with artists including the Bee Gees and their brother Andy Gibb. Their promotions company, Jacobsen Entertainment, continues today, with Col and Kevin Jacobsen as principal members.

Col Joye won several music awards including two ARIA Music Awards and he earned numerous gold and platinum records; he was inducted into the ARIA Hall of Fame in 1988, the first year of such inductions. On 8 June 1981, he was appointed as a Member of the Order of Australia for his entertainment and philanthropic work.

In 1990, Joye sustained serious lower back and shoulder injuries when he fell while cleaning the gutters at his home. Initially given a poor prognosis, he eventually made a full recovery, but elected to retire from performing. A 2001 television documentary series Long Way To The Top recalled some of Australian music's most notable acts, and brought Joye recognition. The popularity of the television series led to a national tour in 2002 with Joye and more than twenty other acts participating.

Col Joye is featured on an Australian stamp honoring the greatest Australian music, and continues to perform and record pop and country music today.
