The East Tennessee Convention was an assembly of Southern Unionist delegates primarily from East Tennessee that met on three occasions during the Civil War. The Convention most notably declared the secessionist actions taken by the Tennessee state government on the eve of the war unconstitutional, and requested that East Tennessee, where Union support remained strong, be allowed to form a separate state that would remain part of the United States split from the rest of Confederate Tennessee. The state legislature denied this request, and the Confederate Army occupied the region in late 1861.

In the United States, Southern Unionists were white Southerners living in the Confederate States of America opposed to secession. Many fought for the Union during the Civil War. These people are also referred to as Southern Loyalists, Union Loyalists, or Lincoln's Loyalists. Pro-Confederates in the South derided them as "Tories". During Reconstruction, these terms were replaced by "scalawag", which covered all Southern whites who supported the Republican Party.
