Sydney Burdekin (18 February 1839 – 17 December 1899) was an Australian politician. He was born in Sydney to merchant Thomas Burdekin and Mary Ann Bossley. He was educated at Darlinghurst and graduated from the University of Sydney in 1859 with a Bachelor of Arts. He became a solicitor's clerk, but apparently did not become a solicitor, instead becoming a pastoralist in northern New South Wales and Queensland. On 24 January 1872 he married Catherine Byrne, with whom he had eight children.
