Zeacuminia murdochi is an extinct species of sea snail, a marine gastropod mollusc in the family Pseudotomidae. Fossils of the species date to late Pliocene strata of the Tangahoe Formation in New Zealand.
In the original description, Powell described the species as follows:
The holotype of the species has an estimated height of , and a diameter of . It can be distinguished from other members of Zeacuminia due to its strong, widely spaced obsolescent axials.
The species was first described by A. W. B. Powell in 1931, who named the species after paleontologist Robert C. Murdoch. The holotype was collected in January 1931 from near the mouth of Waihi Stream near HÃÂwera, Taranaki, and is held in the collections of Auckland War Memorial Museum.

Fossils of the species have been found near HÃÂwera and Waverley, South Taranaki, and on a section of the Manawatà « River near Woodville, Tararua District.
