Martens's warbler (Phylloscopus omeiensis), also known as Omei warbler or Emei Shan warbler, is a species of Old World warbler in the family Phylloscopidae (or Sylviidae). It was first described in 1999.{{ cite journal | last1=Martens | first1=J. | last2=Eck | first2=S. | last3=Päckert | first3=M. | last4=Sun | first4=Y.-H. | year=1999 | title=The Golden-spectacled Warbler Seicercus burkii – a species swarm (Aves: Passeriformes: Sylviidae), part 1 | journal=Zoologische Abhandlungen, Museum für Tierkunde Dresden | volume=50 | pages=281–327 [288] }} It is found in China and Myanmar. Its natural habitats are temperate forests and subtropical or tropical moist montane forests.

Martens's warbler was initially placed in the genus Seicercus. A molecular phylogenetic study published in 2018 found that neither Phylloscopus nor Seicercus were monophyletic.{{ cite journal | last1=Alström | first1=P. | display-authors=etal | year=2018 | title=Complete species-level phylogeny of the leaf warbler (Aves: Phylloscopidae) radiation | journal=Molecular Phylogenetics and Evolution | volume=126 | pages=141–152 | doi=10.1016/j.ympev.2018.03.031 | pmid=29631054 | s2cid=4720300 | url=https://zenodo.org/record/2587011 }} In the subsequent reorganization the two genera were merged into Phylloscopus which has priority under the rules of the International Commission on Zoological Nomenclature.{{cite web| editor1-last=Gill | editor1-first=Frank | editor1-link=Frank Gill (ornithologist) | editor2-last=Donsker | editor2-first=David | year=2018 | title=Bushtits, leaf warblers, reed warblers | work=World Bird List Version 8.2 | url=http://www.worldbirdnames.org/bow/bushtits/ | publisher=International Ornithologists' Union | access-date=8 August 2018 }}
