Chadwick William Morgan (11 February 1933 – 1 January 2025) was an Australian country music singer and guitarist known for his vaudeville style of comic country and western and folk songs, his prominent teeth and goofy stage persona. In reference to his first recording, he was nicknamed as "The Sheik of Scrubby Creek".

In February 2024, Morgan announced that he would retire following the final show of his Farewell to Australia. The final show was on 21 April 2024.

Chadwick William Morgan was born on 11 February 1933 in Wondai, Queensland, as the eldest of 14 children, to Dave and Ivy Morgan. From an early age he was raised by his grandparents, Bill and Eva Hopkins. After his grandfather died in 1947, with his grandmother, he moved back to Scrubby Creek to live with his mother and siblings. Both parents were amateur musicians; his father played accordion and his mother accordion and mandolin, while Morgan learned guitar. He left school at age 14 and found work cutting timber.

According to Morgan, he made a dentist appointment to remove his protruding teeth. "I was tormented so much ... But the farm truck broke down." He later reflected that he was glad he never made another appointment.

From 1948, he worked on cattle farms near Rockhampton and began composing music. Morgan's lyrics use Australian slang including sheilas, drongos, dills and geezers. He was discovered through Australia's Amateur Hour, a radio talent contest, where he sang his original song "The Sheik of Scrubby Creek" and became a national finalist. By November 1952 he had recorded that track together with "You Can Keep Your Wimmln and I'll Stick to My Beer". He signed with Regal Zonophone Records (a subsidiary of EMI), which issued his debut single, "The Sheik of Scrubby Creek", in December. He was described as a "Queensland hillbilly" with a "deadpan, bumpkin style". He also undertook national service with the Royal Australian Air Force (RAAF) at Amberley Base.

Morgan toured extensively during his career, including with the Slim Dusty Show, the All Star Western Show and the Chad Morgan Show. He released 18 studio albums and undertook regular live performances. At the 1987 Country Music Awards of Australia he was inducted into the Australian Roll of Renown, and was awarded an Order of Australia (OAM]) on Australia Day (26 January) in 2004 for "service to country music". Morgan appeared in the films Newsfront (1978) and Dimboola (1979). In the former film he provided a cameo as "Redex singer". For the latter film he depicted Bayonet with "the full force of his unusual personality... [and] the lustre of his success in the entertainment world."

Morgan contributed one verse to the Gordon Parsons song "A Pub with No Beer". He was dubbed the "clown prince of comedy" by Slim Dusty. He recorded a duet with John Williamson, "A Country Balladeer". He had platinum and gold album sales, and is one of Australia's most popular country music artists. Morgan performed at Sydney Opera House with Slim Dusty in April 1978. An album of the concert was released three years later, as On & Off the Road. It was released the same year as Sheilas, Drongos, Dills & Other Geezers, which contained 20 of Morgan's hits from the 1950s and 1960s. In 2009 he wrote a song about his Aboriginal heritage dedicated to his grandparents who raised him as a child, "The Ballad of Bill and Eva". It was recorded with his granddaughter, Caitlin Morgan.

Artists who have impersonated Morgan in their shows include Col Elliott and John Williamson. Barry Humphries used Morgan as his inspiration for Les Patterson's teeth.
