Giuliano Zaccardelli is a retired Canadian police officer who served as the 20th commissioner of the Royal Canadian Mounted Police (RCMP) from 2000 to 2006. Zaccardelli's departure from the RCMP was linked to the force's involvement in the Maher Arar Affair. He was subsequently impugned during inquiries into irregularities in the management of the RCMP's pension and insurance fund.
