Hector Daniel Clouthier (born October 18, 1949) is a former Federal Member of Parliament for the riding of Renfrew—Nipissing—Pembroke in Ontario, Canada.
Taught by Jesuits at Loyola College in Montreal, Clouthier also holds certificates in Strategic Human Resource Management (SHRM) from Harvard University Graduate School of Business Administration and in Alternative Dispute Resolution from the University of Windsor.
Clouthier announced he would once again seek the nomination in 1993, but his candidacy was denied by then-party leader Jean Chrétien who protected Hopkins, who had held the seat for twenty-five years.
He was elected by his fellow Liberal MPs as Chair of the Eastern Ontario caucus, and was named by the Prime Minister as Parliamentary Secretary to the Ministry of National Defence in 2000.
In the 2000 election he was defeated by Canadian Alliance candidate Cheryl Gallant, largely due to his controversial endorsement of gun control, which had become highly unpopular in the region.
Following his time in office, Clouthier served as Executive Director of the Ontario Horse Racing Industry Association (OHRIA) from 2007 to 2010.
In 2019 Marianhill, a senior citizen's complex in Pembroke, Ontario, asked Clouthier to be their campaign chair for a $59 million redevelopment project called "Building Care".
