Diana is an unincorporated community in Upshur County. The community is North of Longview and South of Ore City on highway 259.

The New Diana Independent School District serves area students. The district, located at the intersection of highways 154 and 259, was formed from local schools that were consolidated. Sometimes the community of Diana is incorrectly referred to as New Diana, the local independent school district’s name. The mascot of New Diana ISD is the Eagle. While the population of Diana is unknown due to unincorporation, the school district itself is classified as a 2A by Texas guidelines. New Diana ISD receives quite a few transfers from neighboring schools, however. The school’s longest and most intense rival is its nearest neighbor, the Ore City Rebels
