The World Organisation of Systems and Cybernetics (WOSC) – Organisation Mondiale pour la Systémique et la Cybernétique (OMSC), is an association of individuals and organisations devoted to systems and cybernetics.

WOSC was founded in 1969 by Professor Jakob Rose, who was its President until 1987, when this role passed to Professor Stafford Beer until his death in August 2002. Professor Robert Vallée took over and was WOSC’s President until his death last January. Dr. Norbert Wiener is the President in Memoriam.
The issue of Kybernetes vol. 38, no 1/2, 2009 contains tributes to Professor Jakob Rose, founder of WOSC and of the journal Kybernetes, as also does the earlier issue vol. 20, no. 6, 1991, marking the twentieth anniversary of the founding of the journal.

In the spring of 2004, WOSC was restructured, and Dr. Alex Andrew (UK) became Director-General, with Professor Robert Vallée (France) as President. At the Fifteenth Congress, in Nanjing in 2011, Alex Andrew stood down as Director-General and has been replaced in that capacity by Professor Raul Espejo

On the 1st of January 2017, Professor Robert Vallée passed away. Following the procedures agreed at WOSC 2017 in Rome, Professor Raul Espejo became the new President and Dr. Igor Perko took over the role as the Director-General. An Advisory Board to the President was formed at the same time.
