Calamanthus is a genus of bird in the family Acanthizidae, consisting of three species, all endemic to Australia. These birds are commonly known as fieldwrens.
The genus Calamanthus was introduced in 1838 by the English ornithologist John Gould as a replacement name for Praticola that had been introduced in 1837 by William Swainson to accommodate Praticola anthoides Swainson, a junior synonym of Anthus fuliginosus Vigors and Horsfield, the striated fieldwren. The name Praticola was pre-occupied as it had previous been introduced in 1829 by the German naturalist Johann Jakob Kaup. The genus name combines the Ancient Greek καλαμαια/kalamaia meaning "grasshopper" with the genus Anthus Bechstein, 1805.
A poorly researched genus, the alliance has been recognised as a single species treatment (Schodde, 1975) and later two species or provisionally three separate species. Birds of the World: Recommended English Names lists the following three species:
