Amanita ananiceps is a species of agaric fungus in the family Amanitaceae native to Australia. The species was initially described in 1844 by English naturalist Miles Joseph Berkeley as Agaricus (Amanita) ananaeceps, the specimen having been collected by Ronald Campbell Gunn in 1805 in Tasmania. Italian mycologist Pier Andrea Saccardo placed it in the genus Amanita in 1887. Australian mycologist Alec Wood spelt its species name ananaeceps in his 1997 monograph of Australian Amanita. Within the genus Amanita, it is in the subgenus Lepidella, section Lepidella and subsection Solitariae. It is possibly the same species as Amanita farinacea, and if so, farinacea takes precedence.
