Hormurus polisorum, also known as the Christmas Island cave scorpion, is a species of troglobitic scorpion in the Hormuridae family.

It is endemic to Australia’s Christmas Island in the eastern Indian Ocean.

It was first described in 2001; at the time of its discovery, it was the first troglobitic scorpion species recorded for Australia, and the second outside the Americas.

The scorpions are rare, blind, obligate cave-dwellers, and are restricted to only a few caves on Christmas Island.
