The 29th Regiment Massachusetts Volunteer Infantry was an infantry regiment in the Union army of the United States during the American Civil War. The regiment was organized in December 1861 when three new companies were attached to a battalion of seven Massachusetts companies that had been in active service since May 1861. These seven companies had been recruited to fill out the 3rd Massachusetts and 4th Massachusetts regiments and had signed on for three years of service. When the 3rd and 4th Massachusetts were mustered out in July 1861, the seven companies that had signed on for three years were grouped together to form a battalion known as the Massachusetts Battalion. Finally, in December 1861, three more companies were added to their roster to form a full regiment and the unit was designated the 29th Massachusetts.
The 55th Massachusetts Infantry Regiment was the sister regiment of the renowned Massachusetts 54th Volunteers during the latter half of the American Civil War. The enactment of the Emancipation Proclamation by United States President Abraham Lincoln on January 1, 1863 opened the way for the enlistment of free men of color and newly liberated slaves to fight for their freedom within the Union Army. As the ranks of the 54th Massachusetts quickly reached its full complement of recruits, an overflow of colored volunteers continued to pour in from several other states outside Massachusetts — many of whom simply had not arrived in time — prompting Governor John Albion Andrew to authorize yet another regiment of colored soldiers sponsored by the Commonwealth. Lieutenant Colonel Norwood P. Hallowell of the 54th Massachusetts was promoted to colonel and appointed commander of the 55th Massachusetts on May 30, 1863. Five companies of the 55th Massachusetts were mustered into service on May 31; two more companies were mustered in on June 15; and the last three on June 22.

It consisted of three companies of prewar militia and one newly recruited company together organized under the command of Major Charles Devens. The term "rifles" was a designation frequently given to antebellum militia companies which trained in the use of rifled muskets—a relatively new innovation at the time—as opposed to smoothbore muskets. Only minor differences in training and tactics differentiated such units from a typical infantry company of the time. During the 1840s, "rifle" companies were often expected to train and serve as skirmishers in open order, however by the Civil War, United States army tactics manuals made no distinction between a company of "rifles" and a typical infantry company.

Instead of active combat duty, the regiment served guard and provost duty in various camps and fortifications in and about New Orleans, Louisiana.
