The chestnut-bellied tit (Sittiparus castaneoventris) is a small passerine bird in the tit family Paridae that is endemic to Taiwan.
The chestnut-bellied tit was first described by the English ornithologist John Gould in 1863 and given the binomial name Parus castaneoventris. The title page gives the year as 1862. It was formerly considered as a subspecies of the varied tit but was promoted to species status after the publication of a phylogenetic study in 2014.
The species differs from the varied tit in having underparts of a deep chestnut colour.
