Adam Haslmayr (31 October 1562 – 16 January 1630) was a German writer, who was the first commentator of the Rosicrucian Manifestos.
In 1592 he published in Augsburg the Newe Teutsche Gesang, a printed collection of polyphonic songs in German.
His statement, published in his Answer to the Praiseworthy Brotherhood of Theosophers of Rozenkreuz was included in the same volume as the Fama Fraternitatis, but the original edition is still kept at the Anna-Amalia Library, Germany.
Figulus had brought Haslmayr into contact with Widemann, who in turn introduced him to prince August of Anhalt.
Shortly after, Haslmayr was sent to work at the galleys in Genoa by Maximilian III of Austria, and was released only 4–5 years later.
