Tracy Stone-Manning (born 1965)[2] is an American environmental policy advisor who served as the director of the Bureau of Land Management in the Biden administration from 2021 to 2025.

[5] Upon taking office, Governor Steve Bullock appointed Stone-Manning to succeed Richard Opper as director of the Montana Department of Environmental Quality.

Since 2017, Stone-Manning has worked for the National Wildlife Federation, first as associate vice president for public lands and then as a senior advisor for conservation policy.

[12][13] In 1989, a friend of Stone-Manning's, and fellow environmental activist, was involved in tree spiking in Idaho's Clearwater National Forest.

At the friend's behest, Stone-Manning wrote an anonymous letter to federal officials, informing them of the tree spiking and warning that "a lot of people could get hurt" if logging were to continue.
