Micromacronus is a bird genus in the babbler family Timaliidae endemic to the Philippines. Long considered to be monotypic, its members are known as miniature babblers or miniature tit-babblers. As the scientific as well as the common names indicate, their habitus resembles a diminutive version of the tit-babblers (Macronus). The genus was only described in 1962, upon the description of the first species, which had been collected by collector Manuel Celestino and Godofredo Alcasid, a zoologist at the Philippine National Museum.
