The yellow tit, Taiwan yellow tit, or Formosan yellow tit (Machlolophus holsti) is a species of bird in the family Paridae. It is endemic to central Taiwan. Its length is 5 inches. The yellow tit is mostly yellow, with a crest. The crest and back are blackish blue-grey. It has a restricted range and small population, and appears to be declining due to large-scale capture for export by the wild bird trade, so it is classed as Near Threatened by the IUCN.
