Sand Ridge is an Unincorporated community in north central Wharton County, in the U.S. state of Texas. The tiny community is located northwest of Wharton at the intersection of FM 102 and County Road 259. Situated on the former Cane Belt Railroad, the settlement had its own school in 1905. There were no road signs identifying the place in 2013, but a church and a cemetery with the community name occupied the site. Some homes and several oil wells were located nearby.
