Rabobank (Dutch pronunciation: [ˈraːboːbɑŋk]; full name: Coöperatieve Rabobank U.A.) is a Dutch multinational banking and financial services company headquartered in Utrecht, Netherlands. The group comprises 89 local Dutch Rabobanks (2019), a central organisation (Rabobank Nederland), and many specialised international offices and subsidiaries. Food and agribusiness constitute the primary international focus of the Rabobank Group. Rabobank is the second-largest bank in the Netherlands in terms of total assets.

In terms of Tier 1 capital, the organisation is among the 50 largest financial institutions in the world. As of 2022, total assets amount to €628 billion with a net profit of €2.7 billion.

Rabobank has been designated as a Significant Institution since the entry into force of European Banking Supervision in late 2014, and as a consequence is directly supervised by the European Central Bank.

Rooted in agriculture, Rabobank is set up as a federation of local credit unions that offer services to the local markets.

The bank was rooted in the ideas of Friedrich Wilhelm Raiffeisen, the founder of the cooperative movement of credit unions, who in 1864 created the first farmers' bank in Germany. Being a countryside mayor he was confronted with the abject poverty of the farmers and their families. He tried to alleviate this need through charitable aid, but realised that self-reliance had more potential in the long run, and thus converted his charitable foundation into a farmers' bank in 1864. In doing so he created the Darlehnskassen-Verein, which collected the savings of countryside dwellers and provided enterprising farmers with loans.

This model found a lot of interest in the Netherlands at the end of the 19th century. One of the first of Raiffeisen's followers was Father Gerlacus van den Elsen, who stood at the basis of a number of local farmers' banks in the south of the Netherlands. The model caught on being championed by the clergy and the countryside elites. The mission of the farmers' lending banks was an idealistic one, but they always operated using strict business principles. The cooperative bank model assured a tight bond between invested capital and the community.

The bank's traditional headquarters are Utrecht and Eindhoven. In 1898, two cooperative bank conglomerates were formed:

Raiffeisen-Bank was formed as a cooperative of six local banks, while Boerenleenbank was a cooperative of 22 local banks. These two existed side by side for three-quarters of a century despite their obvious similarities. The reasons for this owed in part to legal disagreements. The most important difference, however, was cultural. The Eindhoven-based Boerenleenbank had a decidedly Catholic signature while the Raiffeisen-Bank had a Protestant background. In the past the Netherlands underwent a process of pillarisation (Dutch: verzuiling), which in practice meant that members of different religious congregations and political movements essentially lived side by side, without contact between the two. A consequence of this pillarisation was that many villages hosted not one but two local banks, one each for Catholics and Protestants. The close-knit community banking that resulted helped these banks to better control their risks. Consequently, when the Dutch banking sector was devastated by a financial crisis in the early 1920s, these local banks survived largely unscathed. The religious backgrounds found their way to their organisational structures, as well; Boerenleenbank was highly centralised, while Raiffeisen-Bank promoted local autonomy.
