Aciphylla anomala is a species of flowering plant in the family Apiaceae. It is endemic to New Zealand. It was formally described by botanist Harry Allan in his 1961 work Flora of New Zealand. The type was collected on Mount Peel. The specific epithet is derived from the Ancient Greek anōmalía, meaning "unusual".

The plant grows as tall spikey leaves that are surrounded by rosettes of stiff, pointed leaves lacking stipules, with a variable number of leaflets per leaf. When flowering, the plant reaches heights of up to 45 cm (18 in). The flower spike is tall and sparsely leaved. Aciphylla polita is somewhat similar in appearance, but can be distinguished by its more dense inflorescence.
