Robert Colin Stigwood (16 April 1934 – 4 January 2016) was an Australian music entrepreneur, film producer, and impresario, long based in the United Kingdom. He was best known for managing musicians such as Cream, Andy Gibb, and the Bee Gees; theatrical productions such as Hair and Jesus Christ Superstar; and film productions, including Grease and Saturday Night Fever. One journalist referred to him as "one of the entertainment industry’s most powerful tycoons," and Playbill called him as "omnipresent in the 1960s and 1970s, with stakes in some of the biggest going concerns in music, theatre and film."
