Seamanite, named for discoverer Arthur E. Seaman, is a rare manganese boron phosphate mineral with formula Mn3[B(OH)4](PO4)(OH)2. The yellow to pink mineral occurs as small, needle-shaped crystals. It was first discovered in 1917 from a mine in Iron County, Michigan, United States and identified in 1930. As of 2012, seamanite is known from four sites in Michigan and South Australia.

La seamanite è un fostato boro manganese estremamente raro, Mn3(PO4)B(OH)6, scoperto inizialmente in Michigan con il nome di "koenigite". Gli unici ritrovamenti sono stati nelle contee di Iron e Marquette dove forma dei cristalli prismatici dal marrone al rosa. Si trova associata alla shigaite. È stata in seguito così denominata in onore del Professor Arthur E. Seaman della suo scopritore.
