Parasteatoda is a genus of comb-footed spiders that was first described by Allan Frost Archer in 1946. The name is a combination of the Ancient Greek "para-" (παρά), meaning "near" or "next to", and the theridiid genus Steatoda. The Japanese name for this genus is O-himegumo zoku.

Parasteatoda species have a characteristic teardrop-shaped abdomen, with the anterior section much higher than the carapace and the spinnerets pointed downwards.
