Peter Sotos (1960?-) is a Chicago, USA-born writer most noted for his obsessive, disturbing ruminations on serial murder and sex.

In 1986 Sotos was arrested and charged with obscenity and possession of child pornography. He was at the time producing a self-published newsletter or "fanzine" named Pure, which numbered among its topics appreciations of serial killers and child abuse. The child pornography charged stemmed from the discovery of a copy of a magazine, Incest #4, which turned up during a search of Sotos's apartment. Charges of obscenity were dropped, but Sotos was eventually found guilty of the possession charge, and was given a suspended sentence and a fine.

Sotos has continued to write, numbering among his works Tool, Parasite, Index, Tick, and Lazy. He has also written an afterword for Ian Brady's book The Gates of Janus.

He was until 2003 a seminal member of the industrial noise band Whitehouse.

The original Pure, along with Tool and Parasite have been reprinted by Jim Goad as Total Abuse.
