Duriatitan is derived from "duria" (the Latin name for Dorset) and the Greek "titan" (giant).
The species epithet, humerocristatus, is derived from "humerus" (upper arm) and "crista" (crest), in reference to the deltopectoral crest on the holotype upper arm bone.

Cetiosaurus humerocristatus (Lyddeker, 1888)
Ornithopsis humerocristatus (Lyddeker, 1888)
Pelorosaurus humerocristatus (Lydekker, 1890).
