Yale School of the Environment (YSE) is a professional school of Yale University. It was founded to train foresters, and now trains environmental leaders through four 2-year degree programs (Master of Environmental Management, Master of Environmental Science, Master of Forestry, and Master of Forest Science) and two 10-month mid-career programs. YSE strives to create new knowledge that will sustain and restore the health of the biosphere and emphasizes the possibility of creating a regenerative coexistence between humans and non-human life and the rest of the natural world. Still offering forestry instruction, the school has the oldest graduate forestry program in the United States.

The school changed its name to the Yale School of the Environment in July 2020. It was previously the Yale School of Forestry & Environmental Studies.
