The 33rd Illinois Infantry Regiment (nicknamed the Teacher's Regiment) was an infantry regiment from Illinois that served in the Union Army during the American Civil War. A number of the soldiers were college students and graduates, and for a time the regiment included a 17-piece band. The unit fought at Fredericktown in 1861, Cotton Plant in 1862, the Vicksburg campaign and Fort Esperanza in 1863, and at Spanish Fort in 1865. The original enlistees were mustered out in October 1864 while the veterans and recruits were mustered out in December 1865.
