The 27-year-old received a hero's welcome as he brought the cup home to Sorel-Tracy, Que., about 100 kilometres northeast of Montreal, the all-news network LCN reported.
"Today marks another moment I will remember for a long time," he told hundreds of onlookers.
"I'm going to take advantage of every moment today to celebrate."
Beauchemin chatted with fans and signed autographs during his day with the cup, a long-standing tradition for members of the winning team.
The Ducks captured the Stanley Cup last month after beating the Ottawa Senators in five games in the best-of-seven final.
