Thomas "Tom" Green (June 8, 1814 – April 12, 1864) was an American soldier and lawyer, who took part in the Texan Revolution of 1835–36, serving under Sam Houston, who rewarded him with a land grant.

After winning several victories, including the Battle of Valverde and the recapture of Galveston, he was promoted brigadier and assigned command of the cavalry division of the Trans-Mississippi Department.

During the April 21 Battle of San Jacinto, Green helped operate the famed "Twin Sisters" cannons, the only artillery present in Sam Houston's army.

That same year, fellow San Jacinto veteran William W. Gant nominated Green for the position of engrossing clerk for the Texas House of Representatives.

When Mexican general Ráfael Vásquez briefly occupied San Antonio in March 1842, Green recruited the Travis County Volunteers and stood as their captain; the unit was not involved in combat.

[1][2][3] In the Mexican–American War, Green recruited a company of Texas Rangers from LaGrange and served as their captain during the 1846 U.S. capture of Monterrey in the state of Nuevo León.

Green's cavalry routed advancing Union troops under Godfrey Weitzel and Cuvier Grover at Koch's (Cox's) Plantation on July 13.

During the Red River Campaign, Green led his division of cavalry from Texas to reinforce Taylor in Louisiana to stop the advance of Maj. Gen. Nathaniel P. Banks toward Shreveport.
