Irish Co-operative Organisation Society

The Irish Co-operative Organisation Society (ICOS) is a cooperative organisation in the Republic of Ireland. With its roots in the Irish Agricultural Organisation Society, ICOS promotes commercial co-operative businesses and enterprise, across multiple sections of the Irish economy.

The Irish Agricultural Organisation Society (IAOS) was founded by Sir Horace Plunkett in 1894 to provide an overarching organisational structure for the numerous small agricultural cooperatives in Ireland at the time. By the mid-twentieth century, cooperativism had greatly expanded in Ireland, and now embraced many businesses and groups outside agriculture. The IAOS was reorganised and renamed as the Irish Co-operative Organisation Society to reflect these changes in the Irish economy.

Today, ICOS member co-ops and their associated companies have more than 150,000 individual members, 12,000 employees in Ireland, a further 24,000 abroad, and a combined annual turnover of €12 billion. Some of the largest businesses in Ireland, such as Aryzta, Glanbia and Kerry Group, are members of ICOS. ICOS has evolved to serve the co-operative sector in seven core categories:

The organisation has offices in Dublin, Cork and Brussels.
