The British artist Spartacus Chetwynd, also known as Lali Chetwynd (born 1973, in London where she now lives and works), has become known for her baroque and surreal performances, which are charged with humorous image quotations from art history, melded with pop culture references.

She studied anthropology at UCL before training as a painter at the Royal College of Art. She adopted the name Spartacus Chetwynd in 2006. Her mother is Luciana Arrighi, an Oscar-winning production designer.

Participating in New Contemporaries in 2004, she was shortlisted for the Beck's Futures prize in 2005. Her contribution to the 2006 Tate Triennial was The Fall of Man, a puppet-play based on The Book of Genesis, Paradise Lost and The German Ideology. In 2009 her work Hermitos Children was included in "Altermodern", the fourth Tate Triennial. The filmed performance was summarised by Adrian Searle as, "The young woman who rode to her own death on the dildo see-saw at the Sugar-Tits Doom Club," and described by Richard Dorment as, "Silly beyond words and teetered at times on the edge of porn – but once you start looking at it I defy you to tear yourself away."
