The Organisation of European Cancer Institutes (OECI) is an international non-profit organization with European Economic Interest Grouping status. It was created in 1979 to promote greater cooperation among European cancer centers and institutes. Its head office is located in Brussels at the Belgian University Foundation.

Background
The OECI is the main European network of accredited cancer centers on the continent. The OECI relies on a network of almost 100 institutions all over Europe,  to ensure cancer patients are provided with the specialized healthcare respective to the type of cancer that they have. Similar to the NCI's network of designated (comprehensive) cancer centres, the OECI developed the Accreditation and Designation Program in order to improve organization and teamwork between cancer centres across Europe. In 2017, the OECI program obtained ISQua Accreditation (ISQua is the umbrella organization responsible for the Joint Commission International accreditation).

The OECI plays a role in helping EU Member State authorities to organize their cancer healthcare systems.
