Donatiello I is a dwarf spheroidal galaxy in Andromeda, located 9.87 million light-years from Earth. It is a possible satellite galaxy of the dwarf lenticular galaxy NGC 404, "Mirach's Ghost". It is otherwise one of the most isolated dwarf spheroidal galaxies known, being separated from NGC 404 by around 211,000 light-years.
Discovered on September 23, 2016, follow-up observations with the Roque de los Muchachos Observatory led to a scientific paper on its discovery being published in December 2018.

It is currently among the 160 galaxies closest to the Milky Way.
