The Cecil-Ross Society was a socialist educational foundation operated by the former majority of the Communist Party of Canada after they were forced to terminate their association with the party in 1992 in a political and legal dispute following the fall of the Soviet Union. The society had been founded by the Communist Party some years before in order to hold various party assets.

The society was was chartered under the Societies Act by George Hewison and other leaders of the Communist Party of Canada. The name came from the intersection of Cecil Street and Ross Street in Toronto which was for many years the location of the Communist Party's headquarters.

The Communist Party had split as the result of a new programme adopted in 2002 which marked the abandonment of Marxism-Leninism as the party's ideology. An orthodox minority resisted this change and were expelled from the party. They, in turn, sued the party and, as the result of a court settlement, the majority relinquished the name Communist Party of Canada to the minority. The majority retained the Cecil-Ross Society and were permitted by the settlement to transfer to it roughly half of the party's assets and the rights to the party's weekly paper Canadian Tribune which ceased publication.

The Cecil-Ross Society held the assets retained by the majority but was not a political party and was restrained by the strictures of the Societies Act only being allowed to utilize its resources for educational and research purposes rather than for party political activity.

The society attempted two publishing endeavors, the magazines New Times and Ginger, both of which failed. The society also created an oral history archive by recording the memoirs of veteran Communists.

After several years, the Cecil Ross Society disbanded its central organization and divided its remaining funds amongst its local branches throughout the country. Most of these branches no longer exist though one reportedly remains in Winnipeg, Manitoba.
