James T. Crossland III (1829–1863) was a lieutenant colonel in the Confederate Army of Tennessee, serving under the commands of Major General Lafayette McLaws and Major General Walthall. He was killed during Braxton Bragg's defense of Lookout Mountain during the Chattanooga Campaign. Crossland, who was Bragg's cousin, reportedly called the defense a "selfish and overconfident move by a General who cared little for the welfare of the men under his command."
