Gerard Endenburg (born 1933) is a Dutch entrepreneur, who developed the Sociocratic Circle Organisation Method (SCM), which is a decision-making method for governing and managing organizations and societies based on equivalence and draws inspiration from cybernetics.

[1] He was a Quaker, and attended a Quaker boarding school, the Werkplaats Kindergemeenschap [nl] [Children's Community Workshop], where he was influenced by Kees Boeke and his wife Betty Cadbury and the ideas of sociocracy.

He became general manager of his family's engineering company, Endenburg Elektrotechniek BV, in the mid-1960s, and in the 1970s started pioneering and applying the sociocratic method of organizing within the company.
