The 121st Regiment Pennsylvania Volunteer Infantry was a regiment of the Union Army during the United States Civil War.

This regiment, chiefly recruited in the city of Philadelphia, and in the county of Venango, was organized at camp of rendezvous, near Chestnut Hill, Philadelphia, early in September 1862, with the following field officers:

Soon after its organization, it was ordered to Washington, D.C., and upon its arrival, went into camp at Arlington Heights. Arms and equipment were not delivered until some weeks after its arrival, but drill and instruction were immediately commenced, and prosecuted with vigor, the regiment becoming noted for good discipline at the drills and reviews of General Silas Casey's Provisional Brigade, to which it was then attached.

On October 1, 1862, the regiment moved to Frederick, Maryland, and a week later joined General George Meade's Division of Pennsylvania troops, above Sharpsburg, and near the battle ground of Antietam. With the exception of slight skirmishing, as the army moved south through Virginia, it had no experience in fighting until it entered upon the Fredericksburg campaign. After reaching Warrenton, where McClellan was replaced by Major General Ambrose Burnside, it passed through Fayetteville, Stafford Court House, Brooks' Station, and White Oak Church, encamping a short time at each place.
