The word hermetic is commonly applied to literary or graphical symbolism that is exceedingly obscure, convoluted, or esoteric. In that context, and not in any other context, hermeticism is the deliberate use of hermetic imagery.
The word hermetic or its derivatives may also refer to:
- Hermeticism, a magical and religious movement stemming from the teachings of Hermes Trismegistus.
- Hermetic Brotherhood of Luxor, an initiatic occult organisation that first became public in late 1884.
- Hermetic Kabbalah, a syncretism of Kabbalah within Hermeticism
