Nicole Marie Eaton (née Courtois; born January 21, 1945) is a former Canadian politician and a Conservative member of the Senate of Canada.
A fundraiser for the Conservative Party, she was appointed on the advice of Stephen Harper to the Senate on December 22, 2008, her term starting on January 2, 2009.
In 2011, Eaton called Canada's national symbol, the beaver, a "dentally defective rat", and suggested that the polar bear should replace it in Canadian iconography.
Her brother, E. Jacques Courtois Jr, is a convicted insider trader having peddled confidential takeover information while a vice-president in Morgan Stanley's mergers and acquisitions department from 1974 to 1977.
Courtois Jr fled to Bogota, Colombia, where he was a fugitive for several years before pleading guilty to insider trading charges in New York in 1983.
