World Rivers Day celebrates the world's waterways. It "highlights the many values of our rivers, strives to increase public awareness, and encourages the improved stewardship of all rivers around the world." The day was started in 2005 after being proposed by river advocate Mark Angelo. Angelo had founded BC Rivers Day in Canada in 1980, and wished for a more global event. The United Nations started the Water for Life Decade in 2005, and approved a proposal for World Rivers Day to go along with it. Millions of people in more than 70 countries now participate in the event.

World Rivers Day is observed next on Sunday, September 29th, 2019. It has been observed the last Sunday in September since 2005.
