Adam Haslmayr (c. 1550, Bozen, South Tyrol – after 1617, Augsburg) was a South Tyrolian writer, who was the first commentator of Rosicrucian Manifestos. He called the revelation of Paracelsus the "Theophrastia Sancta".
Adam Haslmayr was a public notary in South Tyrol. In 1612 he stated that he saw a manuscript of Fama Fraternitatis in 1610, although the book was published in 1614. His statement was included in the same volume as "Fama Fraternitatis".
