Jane Nartare Beaumont (born 10 September 1956), Arnna Kathleen Beaumont (born 11 November 1958) and Grant Ellis Beaumont (born 12 July 1961), collectively known as the Beaumont children, were three Australian siblings who disappeared from Glenelg Beach near Adelaide, South Australia, on 26 January 1966 (Australia Day) in a suspected abduction and murder.

On 25 January, in the midst of a summer heatwave, Jim dropped the children off at Glenelg Beach before heading off on a three-day sales trip to Snowtown. On the morning of 26 January 1966, the children asked their mother to visit Glenelg Beach again. As it was too hot to walk, they took a five-minute, three-kilometre bus journey from their home to
