Nosferattus is a genus of Brazilian jumping spiders that was first described by G. R. S. Ruiz & Antônio Domingos Brescovit in 2005.{{cite journal| last1=Ruiz| first1=G. R.

They range from {{convert|3|to|5.5|mm}} long. Males have a smooth, oval-shaped plate (scutum) on the upper surface of the opisthosoma (abdomen). Nosferattus can be distinguished from other genera in the tribe Sitticini by the presence of highly flattened pedipalps in males, and very long and coiled copulation ducts in females. They are likely related to Aillutticus, which also has a high, broad carapace, rounded laterally behind the posterior lateral eyes, and a slightly convex cephalic region.
