Alexandra Marguerite Clémentine Cousteau (born March 21, 1976) is the daughter of Philippe Cousteau and Jan Cousteau and the granddaughter of French explorer and filmmaker Jacques-Yves Cousteau. An environmentalist, Cousteau advocates the importance of conservation, restoration and sustainable management of water resources for a healthy planet and productive societies.
A member of the third generation of the Cousteau family to devote their lives to exploring and explaining the natural world, Cousteau first went on expedition with her father, Philippe Cousteau, when she was four months old, and learned to scuba dive with her grandfather, Jacques-Yves Cousteau, when she was seven. She grew up traveling the globe, developed a passion for adventure and learned firsthand the value of conserving the natural world.
In 2000, Alexandra co-founded EarthEcho International with her brother Philippe Cousteau Jr. to further her family’s legacy in science, advocacy, and education.
Cousteau was selected as a National Geographic Emerging Explorer for the Class of 2008.
In February 2012, Cousteau joined the international ocean conservation group Oceana as a Senior Advisor to the organization.
