Wavellite is a phosphate mineral, normally translucent green. It is found in fractures in aluminous metamorphic rock, in hydrothermal regions and in phosphate rock deposits.

Named after William Wavell (?-1829) of England who discovered the mineral in a quarry in Devon, England in 1805. It is found in a wide variety of locations notably in the Mount Ida, Arkansas area in the Ouachita Mountains.

Hydrated aluminium phosphate has the chemical formula:

Al3(PO4)2(OH,F)3·5H2O
