Horrorscope is the fifth studio album by thrash metal band Overkill, released on September 3, 1991, through Atlantic and Megaforce Records.

It was the first Overkill album to feature the duo of guitarists Merritt Gant and Rob Cannavino, and the last to be released through Megaforce, although they remained on Atlantic until 1995.

Following the departure of longtime guitarist and songwriter Bobby Gustafson, who left or was fired from the band amid a feud with its founding members Bobby "Blitz" Ellsworth (vocals) and D. D. Verni (bass),[2][3][4] Overkill added two new guitarists in Cannavino (who had been Gustafson's guitar technician) and Gant (previously from thrash metal band Faith or Fear).

AllMusic's Eduardo Rivadavia gave Horrorscope a positive review, awarding it 4.5 stars out of five and stating, "The insecurity felt among Overkill fans by the departure of founding guitarist and key songwriter Bobby Gustafson in 1990 ultimately proved unfounded when the New York thrashers' expanded two-guitar lineup—featuring Rob Cannavino and Merritt Gant—arguably delivered the finest effort of the group's career in 1991's Horrorscope.

Billboard Heatseekers chart[7] and as of 2010 remains Overkill's best-selling album of the Nielsen SoundScan era, having sold over 120,000 copies in the U.S.[8] Promo singles were released for "Coma" and "Infectious",[9][10] while the cover version of "Frankenstein" got airplay on modern rock stations, most notably on KNAC-FM in Los Angeles.
