The Vicksburg Campaign was a series of maneuvers and battles in the Western Theater of the American Civil War directed against Vicksburg, Mississippi, a fortress city that dominated the last Confederate-controlled section of the Mississippi River. The Union Army of the Tennessee under Maj. Gen. Ulysses S. Grant gained control of the river by capturing this stronghold and defeating Lt. Gen. John C. Pemberton's forces stationed there.

The campaign consisted of many important naval operations, troop maneuvers, failed initiatives, and eleven distinct battles from December 26, 1862, to July 4, 1863. Military historians divide the campaign into two formal phases: Operations Against Vicksburg (December 1862 – January 1863) and Grant's Operations Against Vicksburg (March–July 1863).

Grant initially planned a two-pronged approach in which half of his army, under Maj. Gen. William Tecumseh Sherman, would advance to the Yazoo River and attempt to reach Vicksburg from the northeast, while Grant took the remainder of the army down the Mississippi Central Railroad. Both of these initiatives failed. Grant conducted a number of "experiments" or expeditions—Grant's Bayou Operations—that attempted to enable waterborne access to the Mississippi south of Vicksburg's artillery batteries. All five of these initiatives failed as well. Finally, Union gunboats and troop transport boats ran the batteries at Vicksburg and met up with Grant's men who had marched overland in Louisiana. On April 29 and April 30, 1863, Grant's army crossed the Mississippi and landed at Bruinsburg, Mississippi. An elaborate series of demonstrations and diversions fooled the Confederates and the landings occurred without opposition. Over the next 17 days, Grant maneuvered his army inland and won five battles, captured the state capital of Jackson, Mississippi, and assaulted and laid siege to Vicksburg.
