Mater of All Evil is the third studio album of the Italian extreme metal band Necrodeath.
The album came ten years after Necrodeath's previous release, following a hiatus. Rock Hard appreciated the return, both for all who missed their 1980s albums, as well as the album being "an absolute must for older thrash fans". The score was 8 out of 10.
Metal.de interjected "Buy!", giving a 9 out of 10 score. The band took the best from the 1980s extreme metal bands and had a good singer. Their style was "uncompromising, neck-breaking metal, played so well that even Swordmaster and would turn green with envy".
