Unus Annus (literally meaning One Year) is a Youtube channel run by Mark Fischbach (Markiplier) and Ethan Nestor (CrankGameplays). Their objective is to do interesting and unique things for one year until they delete their channel (alongside their videos) and stop selling merch.

The channel will be deleted in November 15 2020.
