Eucamerotus (meaning "well-chambered", in reference to the hollows of the vertebrae) was a genus of sauropod dinosaur from the Barremian-age Lower Cretaceous Wessex Formation (Wealden) of the Isle of Wight, England.

John Hulke erected the genus in 1872 for "NHMUK R.2522", a neural arch found by William Fox near Brighstone Bay, but provided no species name.

[1][2] He later referred NMHUK R.2522 to Ornithopsis, synonymizing Eucamerotus with Seeley's name based on the discovery of additional vertebrae from the Isle of Wight.

Naish and Martill (2001) suggested Eucamerotus was a dubious brachiosaurid, and did not find Blows' characters convincing.

[8] However, a more recent review of Wealden sauropods from England places Eucamerotus as a valid genus of Titanosauriformes incertae sedis.
