Backobourkia is a genus of South Pacific orb-weaver spiders first described by Volker Framenau, Nadine Dupérré, Todd Blackledge & Cor Vink in 2010. It is a common Australian spider, closely related to Eriophora and placed in the "coxal hook clade" of the Araneinae subfamily of Araneidae. Females are generally the same size among all species, but males are much smaller, suggesting male dwarfism throughout the genus. The genus name is a play on the well-known Australian idiom, "Back of Bourke", meaning very remote and beyond the limits of civilization.
