Sophie Joy Martin Delezio (born 3 April 2001) is an Australian schoolgirl who gained media attention when she was involved in an accident at the Roundhouse Childcare Centre in Fairlight, Sydney, Australia.
She suffered third-degree burns to 85% of her body and was hospitalised for several weeks where she lost both her legs.
Delezio is the first daughter of Ron Delezio and Carolyn Martin and the younger sister of Mitchell Delezio and half sister of Catherine Delezio and John Delezio.
Her family has since then become major fundraisers and activists for victims who suffered conditions as Sophie's, and have also assisted in fundraising for the Children's Hospital at Westmead in Westmead.
