What is a word that describes a belief (or nonbelief) in an afterlife?

As far as I can there is no single word for such a denial. For example, had such existed, I am sure that the knowledgeable, well-researched article on the Afterlife at the Stanford Encyclopedia of Philosophy would have used it, or such a term would be used in the Catholic Encyclopedia, but I can find none.

There are more general positions (atheism, materialism, non-Dualism, ...) which tend to lead to such an assertion, but none so precise as swallowing the desire for a single, obscure word and expressing it with a few common ones as you have done well in your question.

I'd say the term that best fits what you're looking for is strong atheist.

The general categories are as follows (the definitions change a bit but these are my interpretations):

• Strong atheist ("no god exists")
• (Weak) atheist ("there's no evidence for a god")
• Agnostic ("I'm not sure whether there's evidence for a god")
• Deist ("there's evidence for some kind of higher power / I believe in some kind of higher power")
• Theist ("there's evidence for a specific god / I believe in a specific god")

"Humanism" is a term generally used to describe a philosophy that rejects religious superstitions and the presence of an afterlife. If you look it up using this term, you will find many historical references.
