Cyrtophora hirta is a species of tent spider found in the Australia.

The southern range of distribution is near Sydney,[1] though there are New Guinea and Tasmanian records on the Atlas of Living Australia.

Many spiders and their tent shaped webs may be found in close proximity.

The spider retreats into a white mass of web in the centre, often stained by the remains of prey.

The egg sac is plano-convex in shape, 10 mm in diameter, coloured greenish-white.
