Dobbin is an unincorporated community in Montgomery County, Texas, United States.
It is situated at the junction of State Highway 105 and FM 1486, approximately 12 miles north of Magnolia.
A few years later, the Trinity and Brazos Valley Railway built through Bobbin on its way to Mexia and Houston, making the community a railroad junction.
By the late 1940s, the community had three churches, two schools, two sawmills, two factories, nine businesses, a railroad station, and a population of 175.
[1] Despite its unincorporated status, Dobbin continues to have a functioning post office (zip code: 77333).
