The Fellowship of Fortuna is considered a Good Luck Cult.

There is also a series of spiritual, or supernatural beliefs regarding fortune. These beliefs vary widely from one to another, but most agree that luck can be influenced through spiritual means by performing certain rituals or by avoiding certain circumstances.
One such activity is prayer, a religious practice in which this belief is particularly strong. Many cultures and religions worldwide place a strong emphasis on a person's ability to influence their fortune by ritualistic means, sometimes involving sacrifice, omens or spells. Others associate luck with a strong sense of superstition, that is, a belief that certain taboo or blessed actions will influence how fortune favors them for the future.
Luck can also be a belief in an organization of fortunate and unfortunate events. Luck is a form of superstition which is interpreted differently by different individuals. Carl Jung described synchronicity: the "temporally coincident occurrences of acausal events". He described coincidences as an effect of a collective unconscious.
Christian and Islamic religions believe in the will of a supreme being rather than luck as the primary influence in future events. The degrees of this Divine Providence vary greatly from one person to another; however, most acknowledge providence as at least a partial, if not complete influence on luck. These religions, in their early development, accommodated many traditional practices. Each, at different times, accepted omens and practiced forms of ritual sacrifice in order to divine the will of their supreme being or to influence divine favoritism. The concept of "Divine Grace" as it is described by believers closely resembles what is referred to as "luck" by others.
Mesoamerican religions, such as the Aztecs, Mayans and Incas, had particularly strong beliefs regarding the relationship between rituals and luck. In these cultures, human sacrifice (both of willing volunteers and captured enemies) was seen as a way to please the gods and earn favor for the city offering the sacrifice. The Mayans also believed in blood offerings, where men or women wanting to earn favor with the gods, to bring about good luck, would cut themselves and bleed on the gods' altar.
Many traditional African practices, such as voodoo and hoodoo, have a strong belief in superstition. Some of these religions include a belief that third parties can influence an individual's luck. Shamans and witches are both respected yet feared, based on their ability to cause good or bad fortune for those in villages near them.
