Doktor Sleepless is a monthly comic book series written by Warren Ellis with art by Ivan Rodriguez that is published by Avatar Press, launched in July 2007.

According to series writer Warren Ellis, Doktor Sleepless may be a man named John Reinhardt, a trust-fund baby and boy genius who is shunned by the counter-culture he helped found.

Since his mysterious disappearance, he has reinvented himself as "Doktor Sleepless" and, to the dismay and utter confusion of the authorities, seemingly rules the airwaves (through his mastery of all things technological) with his thought-provoking, radical rhetoric.

It is revealed he is deliberately instigating violence by the grinder counter-culture and is providing them with the means to do so, as well as releasing a bioweapon — "St Theresa's Eyes" — that causes people to "see angels" (actually winged, mechanical constructs which may or may not be hallucinations).

He is unaware his companion ("Nurse") murdered an old colleague of his that he intended to contact; directly after outlining his grand scheme, he is shocked when he sees one of the angel constructs himself.
