The Fellowship of Isis (FOI) is an international spiritual organization devoted to promoting awareness of the Goddess. It is dedicated specifically to the Egyptian goddess Isis because the FOI co-founders believed Isis best represented the energies of the dawning Aquarian Age. The FOI is a multi-faith, multi-racial, and multi-cultural organization, and despite worshipping pagan deities, does not consider itself to be a Neopagan faith, with its co-founder Olivia Robertson stating in 2002:

All members in the Fellowship of Isis have equal privileges within it, and membership is free. Membership is open to anyone who wishes to join – once an individual has read through the Fellowship of Isis Manifesto and finds themselves in agreement with the principles laid out within it. There are no vows of secrecy. Members are free to resign at any time, if they so choose and to rejoin again at a later time.
