The name of the mineral comes from the localilty of Tripuhy, Minas Gerais, Brazil, where it was discovered. Hussak and Prior  first described the mineral tripuhyite as an oxide of iron and antimony, and assigned it the composition Fe2Sb2O7. When a mineral with composition FeSbO4 was later discovered in Squaw Creek, New Mexico (USA), it was considered erroneously as a new mineral and it was given the name squawcreekite. However, other studies had shown that the original tripuhyite was also FeSbO4. In 2002, the Commission on New Minerals and Mineral Names (CNMMN) of the International Mineralogical Association (IMA), approved the redefinition of tripuhyite as FeSbO4 and the discreditation of squawcreekite.
