Eucalyptus todtiana, commonly known as coastal blackbutt[2] pricklybark[3] or dwutta,[4] is a species of tree or a mallee that is endemic to the west coast of Western Australia.

[7][8] The specific name honours Emil Todt, a botanical artist who drew some of the plates for Mueller's Atlas of Eucalypts.

[9] This species is part of the Eucalyptus subgenus series Diversiformae, subseries Neuropterae, a group of mallees that all have adult leaves held erect, buds with a single unscarred operculum and pyramidal seeds.

[2][3][5] The slow growing,[10] long lived species is a habitat tree for many local fauna such as nectar-feeding birds, bats, lizards and insects.

[6] This eucalypt is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.
