Jeremy Buckingham (born 22 November 1973) is an Australian politician who has served as a member of the New South Wales Legislative Council since 2023, having previously held the same office from 2011 until 2019.

Buckingham was a member of the Greens until he resigned from the party in 2018. He returned to parliament at the 2023 election as a member of the Legalise Cannabis Party.

Buckingham was born in Launceston, Tasmania and spent his early life living in the historic homestead 'Hillgrove', adjacent to the Taroona Shot Tower site south of Hobart. Growing up in this historic setting, he developed a strong sense of place and history, which later influenced his commitment to preserving the environment and cultural heritage. He attended Taroona Primary, Taroona High School and graduated from The Hobart College.

After school he spent two years working as a benchman in a small country sawmill run by Kim Booth (later a Greens member of the Tasmanian House of Assembly) in central Tasmania.

In 1994, Buckingham fronted heavy metal band Amplifire as singer, with other band members including his brother Jessie 'Tambo' Buckingham, as well as Michael Kelly, Brett Collidge and John Salter.

Buckingham moved to Sydney in the mid 1990s, where he worked as forklift driver, hardware store salesman and builders' labourer.^{[citation needed]}

Buckingham relocated to Orange in the central west of New South Wales in 1997, where he worked as production manager for monumental stonemason McMurtrie & Co. In his time at the stonemason, Buckingham worked on public works such as the Australian War Memorial in London, the Federation Square project and the Sydney Olympic Games site.

After a back injury rendered him unfit for heavy lifting, Buckingham enrolled and completed an Advanced Diploma in Ecological Agriculture and Land Management at the University of Sydney, which he completed in 2006. He continued to work as a stonemason until his election to state parliament in 2011.
