Mark Angelo, CM OBC (born 14 March 1951) is a Canadian river conservationist, writer, speaker, teacher and paddler.

[16][17] In 2005, Angelo helped set up the World River Day,[18][19] a now annual event on the final Sunday in September, celebrated by millions people in more than 100 countries.

[24] In late November 2011, Angelo announced his retirement from full-time work and was honored with the title, Chair Emeritus of the Rivers Institute.

[27] In 2016, the feature film documentary, RiverBlue, chronicled Angelo’s three year around-the-world journey by river from 2012 to 2015 during which he uncovered and documented the extensive freshwater pollution impacts of the global fashion industry.

[28][5][7] RiverBlue went on to win several international awards including best documentary feature at the United Kingdom’s largest independent film festival, Raindance.

[37] In late 2021, Angelo published the acclaimed illustrated children’s book, The Little Creek That Could; the story of a stream that came back to life.

The book is based on the real-life 50 year effort led by Angelo and others to restore and clean-up Burnaby’s once severely polluted Guichon Creek.

[45][46] The compilation of this list, done in concert with the 100,000 member Outdoor Recreation Council of British Columbia, helps provide important profile for a number of key river issues across the Province.
