Name:
Apophyllite was named in 1806 by Rene Just Haüy from the Greek for "away from" (ἀπό, apo) and "leaf" (φύλλον, phyllos), in allusion to the way it exfoliates upon heating. Chemical variants were recognized by Pete J. Dunn, Roland C. Rouse, and Julie A. Norberg in 1978.

Fluorapophyllite-(K) - Hydroxyapophyllite-(K) Series.
The name was revised from apophyllite-(KF) to fluorapophyllite-(K) (Hatert et al. 2013).
The name was revised from apophyllite-(KF) to fluorapophyllite-(K) (Hatert et al. 2013).
