Evander McNair (April 15, 1820 – November 13, 1902) was a brigadier general in the Confederate States Army during the American Civil War.

During the Mexican War McNair joined the 1st Mississippi Rifles under the command of Colonel Jefferson Davis, who would later become President of the Confederacy.

When General Benjamin McCulloch was killed and Colonel Louis Hébert was captured, McNair became the commander of the brigade.

On December 31, 1862, McNair and his troops participated in McCown's charge on the Union right at the Battle of Stones River near Murfreesboro, Tennessee.

In May 1863 McNair and his division were sent to reinforce the Army of Tennessee under General Joseph E. Johnston for the relief of the siege at Vicksburg, Mississippi.
