Catherine Pinhas Mulcair (born September 27, 1955) is a Canadian psychologist based in Quebec. She is the wife of former Canadian Opposition leader Thomas Mulcair.
After Mulcair became the leader of the Official Opposition in 2012, Pinhas began using the name Catherine P. Mulcair instead of Catherine Pinhas, which she previously preferred.
She was born in France to a Sephardic Jewish family of Turkish origin that had survived the Holocaust.
Pinhas works in private practice in Verdun, Quebec as well as in long-term and palliative care at a community and was a member of the board of administrator at the Order of Psychologists of Quebec and the regional health board for southwest Montreal until May 2015.
She and Thomas Mulcair met as teenagers when she visited Quebec from France in order to attend a cousin's wedding. She immigrated to Canada soon after and the couple married in 1976 when they were both 21.
She is a dual citizen of Canada and France and ran unsuccessfully for a seat on the Assemblée des Français de l'étranger, a body representing French citizens living abroad, in 2009.
Under the name Catherine Mulcair, she ran on a slate aligned with then-French President Nicolas Sarkozy's centre-right party, the Union for a Popular Movement.
