The Open Source Order of the Golden Dawn (OSOGD) is an esoteric community of magical practitioners, many of whom come from pagan backgrounds. It is an initiatory teaching Order that draws upon the knowledge, experience, practices and spirit of the system of magical training and attainment developed by the original Hermetic Order of the Golden Dawn.

The OSOGD was founded by Sam Webster in 2002 and based on the principles of the open-source software movement. The organization grew out of a series of workshops on ceremonial magic held by Webster in 2001.
According to Sam Webster,
The Open Source Order is founded on the principle that true spirituality is omnipresent and access to it cannot be owned or controlled by any group or individual. Sufficiently skilled practitioners can and do modify the practices to serve specific purposes or to take advantage of the century-plus development in the craft to improve their effect.
According to The Manifesto of the Open Source Order of the Golden Dawn, the Order has undertaken to revise the teachings of the original Victorian era Hermetic Order of the Golden Dawn system to work more effectively in the 21st century. This redaction of the original rituals has taken on the aspect of a number of principles, listed in the Manifesto as Open Source Magick, New Aeon, Freedom of Information, Thelema, Duty, Universalism, and Form and Function.
In temple work, the OSOGD uses Egyptian, Enochian and Thelemic godforms in preference to the Judeo-Christian Archangels typical of the original Hermetic Order of the Golden Dawn. According to the Manifesto, OSOGD teaches "a progressively tiered system of spiritual development designed to invoke the Higher or Divine Genius latent in every human being."
To actually join the Order, a person must have regular access to its Lodge, which is located in the San Francisco Bay Area. The Order does not conduct distance initiations, and requires that all initiates attend initiation rituals in person.
The Open Source Order of the Golden Dawn draws heavily from Eastern sources, Thelema, Paganism, and the works of Aleister Crowley.
