Wellborn is located along FM 2154 (Wellborn Road) on the Southern Pacific Railroad, approximately four miles south of College Station and eight miles northwest of Millican in southern Brazos County.^[3]

The community came into existence in 1867 as a construction camp on the Houston and Texas Central Railroad and was a part of the northeastern corner of a land grant given to A.M. McMahon. The first store, cotton gin, and lumberyard were established by John and Thomas Royder of the Rock Prairie community. The town's name has been attributed to a well at the construction camp, a foreman named E.W. Wellborn, or a landowner named W.W. Wilburn.^[2][3]

In 1867, a post office opened in the community under the name Wellborn Station. Three years later, the name was shortened to Wellborn. By the mid-1880s, Wellborn had developed into a shipping point for cattle and had a population of approximately 50. In 1885, Wellborn had two churches, a gristmill, a cotton gin, and 50 residents. It was home to 400 people by 1910. Soon after, Wellborn went into decline. The number of inhabitants hit a low of 40 in 1950, partly due to the rise of nearby College Station and Bryan. An estimated 100 people lived in Wellborn as of the late 1980s. Twenty businesses as well as a community center and water utilities were operational in 1990. The population hovered around 100 throughout the 1990s and into 2000.^[2] In 2001, a new water tower was built in Wellborn.^[3]

Although Wellborn is unincorporated, it has a post office, with the ZIP code of 77881.^[4] The Wellborn Cemetery, which dates back to the early 1870s, is designated a state historic landmark.^[5] In 2009, the Citizens for Wellborn Committee was founded as a non-profit group to explore incorporation. Because Wellborn lies in the extraterritorial jurisdiction of College Station, the city council of College Station must grant permission to the Wellborigines for them to exercise their right to vote.^[6]

Citizens of Wellborn have fought with the city of College Station to protect itself from being incorporated into the city; the College Station City Council voted 5-2 to annex Wellborn and incorporate it into the city on April 14, 2011.^[7]

On April 30, 2007, the second episode of Diners, Drive-Ins and Dives was filmed at the Hullabaloo Diner in Wellborn.^[8]
