Camilla Erculiani (died post-1584) was an Italian apothecary, writer, natural philosopher and women's advocate during the early modern period.
 This "self-described pharmacist" published a book, in the form of letter-essays, about her views on topics of science and natural philosophy.
 Erculiani's "Lettre di philosophia naturale" or "Letters on Natural Philosophy" was published in 1584.

 Although the trial records are lost, it is speculated that Erculiani was likely pardoned.
