Ceres is a non-profit sustainability advocacy organization based in Boston, Massachusetts, and founded in 1989.

Ceres was founded in 1989 when Joan Bavaria, then-president of Trillium Asset Management, formed an alliance with leading environmentalists with the goal of changing corporate environmental practices.

She named the organization the "Coalition for Environmentally Responsible EconomieS", or CERES.

In 1993, following lengthy negotiations, Sunoco became the first Fortune 500 company to endorse the Ceres Principles.
