Cyrtophora, the tent-web spiders, is a genus of orb-weaver spiders first described by Eugène Simon in 1895. Although they are in the "orb weaver" family, they do not build orb webs. Their tent-like, highly complex non-sticky web is sometimes considered a precursor of the simplified orb web. These webs are aligned horizontally, with a network of supporting threads above them. These spiders often live in colonies. Females have a body length of mostly about 10 millimetres (0.39 in) long. Some members, including Cyrtophora cicatrosa, exhibit the ability to change colour rapidly.

A kleptoparasitic spider (Argyrodes fissifrons) was found to live in a mutualistic relationships with Cyrtophora species. Some of the species are considered social spiders, building large structures where the territories of the offspring are built along the margin of the mothers web.
