In Ancient Greek mythology, Olethros /ˈɒlɪˌθrɒs/ (Greek: ὄλεθρος) was the Greek concept or personification^{[citation needed]} of "havoc" or "ruin".

Olethros translates roughly in ancient Greek to "destruction", but often with a positive connotation, as in the destruction required for and preceding renewal.
