Clatrotitan is an extinct genus of titanopteran insect, known from the Triassic of Australia.

[1] It is originally described from a species, C. andersoni, then later study considered that Mesotitan scullyi as species of Clatrotitan too.

But another study synonymized Mesotitan and Clatrotitan.

A study in 2021 proposed to keep the two genera Clatrotitan and Mesotitan separated.

[2] C. andersoni had a large forewing, which was 13.8 centimetres (5.4 in) long.
