Socca is an Australasian genus of orb-weaver spiders with known species in both Australia and New Zealand.
In an overview of morphological data, the genus was characterised by a diagnostic presence of five tubercles posteriorly on the abdomen, plus specific anatomical features of the male pedipalp, notably a tri-partite terminal apophysis. In mature females, the epigyne plate is about as wide as long and the scape elongate. Together, these features help differentiate Socca from other genera of orb-web spiders.
Socca occur in a range of different habitats.
A few species were previously assigned to other genera, such as Araneus or Epeira.
