A benefit society, fraternal benefit society or fraternal benefit order is a society, an organization or a voluntary association formed to provide mutual aid, benefit, for instance insurance for relief from sundry difficulties. Such organizations may be formally organized with charters and established customs, or may arise ad hoc to meet unique needs of a particular time and place. Many major financial institutions existing today, particularly some insurance companies, mutual savings banks, and credit unions, trace their origins back to benefit societies, as can many modern fraternal organizations and fraternal orders which are now viewed as being primarily social; the modern legal system essentially requires all such organizations of appreciable size to incorporate as one of these forms or another to continue to exist on an ongoing basis.
Benefit societies may be organized around a shared ethnic background, religion, occupation, geographical region or other basis. Benefits may include financial security and/or assistance for education, unemployment, birth of a baby, sickness and medical expenses, retirement and funerals. Often benefit societies provide a social or educational framework for members and their families to support each other and contribute to the wider community.
Examples of benefit societies include trade unions, friendly societies, credit unions, self-help groups, landsmanshaftn, immigrant hometown societies, fraternal organizations built upton the models of fraternal orders such as the Freemasons and the Oddfellows, coworking communities, and many others.
