Sidney Haight (August 21, 1847 – September 17, 1918) was awarded the Medal of Honor during the American Civil War for actions during the Siege of Petersburg.

On 23 October 1863, Haight lied about his age and said he was 17 (he had turned 16 in August)[1] and mustered into Federal service in Company E, of the 1st Michigan Volunteer Sharpshooters Regiment for three years.

When the rebels counterattacked, "instead of retreating, remained in the captured works, regardless of his personal safety and exposed to the firing, which he boldly and deliberately returned until the enemy was close upon him."

[4] Haight was noticed by men for his courage and seeming invincibility, as he and a Native American comrade from Company K, Antoine Scott,[5] maintained a constant, accurate covering fire on the rebels until all who could have escaped.

Instead of retreating, Corporal Haight remained in the captured works, regardless of his personal safety and exposed to the firing, which he boldly and deliberately returned until the enemy was close upon him.
