Botanic Gardens Conservation International (BGCI) is a plant conservation charity based in Kew, Surrey, England.

Founded in 1987, BGCI is a registered charity in the United Kingdom, and its members include the Royal Botanic Gardens, Kew, and the Royal Botanic Garden, Edinburgh, as two of its key supporters.

Dedicated to plant conservation and environmental education, the charity works to support and promote the activities of its member gardens. Its official stated mission is to “mobilize botanic gardens and engage partners in securing plant diversity for the well-being of people and the planet.”

As a global organization, BGCI has projects in a variety of different countries, with major ongoing projects in China (where half of the wild magnolias are threatened), North America, the Middle East, and Russia. Two of its major projects are the creation of online searchable databases listing the world’s botanic gardens (Garden Search) and plants in cultivation among participating botanic gardens (Plant Search).

In 2017 Botanic Gardens Conservation International published a list of 60,065 tree species worldwide obtained from information supplied by its member organizations. The aim of the project was to identify trees that are in danger of extinction and promote efforts to conserve these trees.
