Hutchinsonite is a sulfosalt mineral of thallium, arsenic and lead with formula (Tl,Pb)2As5S9. Hutchinsonite is a rare hydrothermal mineral.

It was first discovered in a sample from Binnental, Switzerland in 1903 and named after Cambridge mineralogist Arthur Hutchinson, F.R.S. (1866–1937) in 1904.
