Iuticosaurus (meaning "Jute lizard") is a genus of titanosaur sauropod dinosaur from the Early Cretaceous of the Isle of Wight.

[3] On reading the paper to the Geological Society of London, Lydekker was criticised by Harry Govier Seeley and John Hulke for his choice and in 1888 he referred to the fossils as Titanosaurus sp.

In 1993 Jean le Loeuff redescribed the material and named a separate genus: Iuticosaurus, the generic name referring to the Jutes who settled the island in the fifth century and established a Jute dynasty in the sixth century.

Le Loeuff made Iuticosaurus valdensis the type species, and chose BMNH 151 as the lectotype.

[2] Most researchers have concluded that both species of Iuticosaurus cannot be distinguished from other titanosaurs and are therefore nomina dubia.
