'''''Tychaedon''''' is a genus of passerine birds in the Old World flycatcher family Muscicapidae that are found in Sub-Saharan Africa. It contains species that were formerly placed in the genus ''Cercotrichas''.
==Taxonomy== The species now placed in this genus were previously placed in the genus ''Cercotrichas''. A molecular phylogenetic study of the family Muscicapidae published in 2023 found that ''Cercotrichas'' was paraphyletic.<ref>{{Cite journal | last1=Zhao | first1=M. | last2=Gordon Burleigh | first2=J. | last3=Olsson | first3=U. | last4=Alström | first4=P. | last5=Kimball | first5=R.T. | date=2023 | title=A near-complete and time-calibrated phylogeny of the Old World flycatchers, robins and chats (Aves, Muscicapidae) | journal=Molecular Phylogenetics and Evolution | volume=178 | article-number=107646 | doi=10.1016/j.ympev.2022.107646 | doi-access=free }}</ref> In the rearrangement to create monophyletic genera, some species were moved to the resurrected genus ''Tychaedon''.<ref name=ioc>{{cite web| editor1-last=Gill | editor1-first=Frank | editor1-link=Frank Gill (ornithologist) | editor2-last=Donsker | editor2-first=David | editor3-last=Rasmussen | editor3-first=Pamela | editor3-link=Pamela C.
