Allanpringite is a phosphate mineral that was named after the Australian mineralogist, Allan Pring of the South Australian Museum.

Allanpringite is a Fe3+ analogue Al-phosphate mineral wavellite, but it has a different crystal symmetry – monoclinic instead of orthorhombic in wavellite.

It forms needle-like crystals, which are always twinned and form parallel bundles up to about 2 mm long. They are often found in association with other iron phosphates in abandoned iron mines.[2][4]
