Notrees is an unincorporated community in west-central Ector County, Texas, United States.

Local merchant Charles E. Brown petitioned for a post office and selected the descriptive name of Notrees.

Reportedly, the community had a single native tree before it was destroyed during the construction of a Shell Oil Company gas plant.

The community began to decline by the 1980s as a result of oil companies abandoning the camps that once provided housing for employees and their families.

The area has a 153 MW wind farm, connected to one of the world's largest grid energy storage systems and used mostly for electrical-grid frequency response.
