'''''Trimastix''''' is a genus of [[Excavata|excavate]] [[protist]]s, the sole occupant of the order Trimastigida.{{cite journal |author=Cavalier-Smith T |title=The excavate protozoan phyla Metamonada Grassé emend.

These organisms do not have classical [[mitochondria]], and as such, much of the research involving these microbes is aimed at investigating the evolution of mitochondria.{{cite web| url=http://tolweb.org/Trimastix/97437| author=Alastair Simpson| author2=Vladimir Hampl| author-link=Alastair Simpson| author2-link=Vladimir Hampl| name-list-style=amp| title=Tree of Life: Trimastix| publisher=Tree of Life | access-date=July 24, 2012}}
