Millettarian thanatology, also primarily known as Astronic thanatology, Millettic thanatology, and less frequently referred to as Millettothanatology, is the branch of Millettarian eschatology that specifically deals with the different beliefs regarding what will occur to both sentients and non-sentient beings after their corporeal death, as well as the general nature of the afterlife.

Astronic thanatology is dominated by the naturalistic viewpoint which, in an eschatological, thanatological, and Millettic philosophical context, refers to the disbelief in any form of afterlife and therefore considers sentient beings to be no different from non-sentient beings regarding the question of what will occur to them after their death. There are three orientations within the naturalistic worldview including theistic naturalism, atheistic naturalism, and non-theistic naturalism, the first of which is the orientation upheld by the Millettarian Tradition.
