Marc Kielburger CM OMC (born 1977) is a Canadian author, social entrepreneur, columnist, humanitarian and activist for children's rights.

[3][4][5] At age 13, he became involved in environmental activism, founding clubs, starting petitions and eventually becoming the youngest person ever to receive the Ontario Medal for Good Citizenship.

Following several months of physical therapy, he resumed playing rugby in college and law school, but was often on the bench as his weak ankle was repeatedly reinjured.

[16] While Marc Kielburger was studying at Harvard, his younger brother Craig read a story in the newspaper about the murder of a former child labourer in Pakistan.

[18] Marc's work with Free the Children has included co-creating ME to WE, a social enterprise organization that supports WE Charity with half its profits, and WE Day, an annual youth empowerment event held in large stadiums in cities across Canada, the U.S. and the U.K. Kielburger later co-founded Leaders Today, an organization that trains young people to develop skills and confidence to effect social change.

[30] On January 13, 2025, the National Basketball Association team Washington Wizards and Monumental Sports & Entertainment Foundation announced that they, too, would join the partnership with Realizing the Dream.

Contributors to the book include the Dalai Lama, Julia Roberts, Yara Shahidi, Jay Shetty, Al Sharpton and Sanjay Gupta.

[32][33] On January 13, 2025, iHeartMedia announced that it had partnered with Legacy+ and The Martin Luther King III Foundation to produce a podcast series called My Legacy.

[36] The selection of WE Charity led to accusations of favouritism, since the government would be outsourcing a massive federal aid program to a private organization with ties to Canadian Prime Minister Justin Trudeau and his family.

[36] On June 30, 2020, the Canadian Press published a video of Marc Kielburger telling youth leaders earlier in the month that Trudeau's office had contacted WE Charity to see if the organization would administer the student aid program.
