The Battle of Shakopee occurred on the morning of Thursday, May 27, 1858, between Murphy's Landing in Shakopee, Minnesota and Eden Prairie, Minnesota. It was the last major conflict between the Dakota and Ojibwe Native American tribes.

The two tribes held nothing short of utter contempt for each other for decades. Settler-colonists in the region noted sparring between the tribes as far back as the fifteenth century. Both moved seasonally to hunt for deer, gather wild rice, and make maple sugar. Occasionally, these resources were competed for. Brief ceasefire periods were often obliterated by local, bloody skirmishes. Fighting was prevalent hundreds of years before the founding of the Minnesota Territory. The intensity of the conflict in the specific region to be later known as Minneapolis and its surrounding areas was one of the many factors leading to the creation of Fort Snelling at the confluence of the Minnesota and the Mississippi rivers in 1825.

The aforementioned settler-colonist immigration, reliance on the fur trade, and the founding of the Minnesota Territory on March 3, 1849, further intensified the two tribes' competition for resources. The addition of firearms added to the brutality of the conflicts. By the late 1850s, treaties with the United States government had confined the Dakota tribe to a reservation straddling the upper Minnesota River, and the Ojibwe to lands further north and east. However, this nominal separation did not prevent Ojibwe-Dakota tensions from turning violent again in 1858; Minnesota entered the Union as the 32nd state on May 11 of that year, just over two weeks before the Battle of Shakopee.

Though their explanations of the battle's direct cause contradicted each other, many observers stated that the Ojibwe looked for retribution against the Dakota for a recent series of attacks on their people. In one such attack in April, a family of eleven women and children near Crow Wing, Minnesota were killed in their sleep.

On the night of Wednesday, May 26, between 150 and 200 Ojibwe warriors laid in wait in the woods on the north bank of the Minnesota River, outside of a Dakota encampment on the south side of the river at Murphy's Landing. The Dakota camp was occupied by 60 to 70 men. The Ojibwe planned to ambush the camp early in the morning.

Sometime between 4:30 and 5:00 am, ten men from the Ojibwe party opened fire, fatally wounding a young Dakota man fishing from a canoe along the south side of the river. The Ojibwe proceeded to scalp him. The camp immediately awoke, and 30 to 50 Dakota warriors armed themselves and charged for the riverbank.

Both sides exchanged gunfire from their respective sides of the Minnesota River; the Dakota were out of range and boarded Murphy's Ferry to cross and meet their attackers on the north of "Big Creek". As the Dakota disembarked on the north riverbank, the rest of the Ojibwe party ambushed them, to limited success.

The Ojibwe made several attempts to dislodge their foes by strong detachments, but without success. The Dakota, although inferior in numbers, fought with characteristic vigor and desperation. In the midst of the skirmish, a Dakota warrior fell, and the tribe attempted to carry his body back to their camp. The Ojibwe gave chase, successfully attempting to steal the body, but three brothers of the fallen warrior stayed behind in the midst of the Dakota retreat to retrieve the body. The Dakota brothers called to their fellow men to assist them, before they too were killed. Enraged, the Dakota rescinded their retreat and fully engaged the Ojibwe with ferocity.

The sounds of gunfire attracted the attention of Shakopee residents, who observed the skirmish from the safety of the bluffs above.

At 10 am, the fighting ceased. In the end, an estimated seven to 11 men lost their lives: four or more Ojibwe killed and at least one, Kawetahsay, wounded after taking a shot to the mouth, and two to three Dakota killed and 10 wounded. The Ojibwe retreated north to Lake Minnetonka, and the Dakota returned to their encampment to fortify it in the event of a follow-up attack.

Among the trophies of the Dakota was the body of Noon Day, the leader of the Ojibwe warriors. Dakota chief Wau-ma-nuag cut out Noon Day's heart and drank the blood from it, scalped and decapitated the corpse, and carried it on a pole back to Shakopee. The victory was celebrated by a scalp dance, lasting several days, and then Noon Day's corpse was burned.

Daniel Buck, Supreme Court justice of Minnesota, remarked that the Dakota appeared "demoralized" after the battle, "with their blankets shot and torn, and carrying their wounded home toward their reservation. On their way to their reservation the [Dakota] held a war dance on the levee in the city of Mankato. They had the hand of a[n Ojibwe man] fastened to a long pole, and danced around it..."

Eyewitness Phillip Collins, who had witnessed the mutilation of Chief Noon Day's body, retrieved a pouch containing the pipe, kinnickinnkh and more personal effects of a fallen Dakota warrior, a crude map on birch bark that bore, besides the localities of hills, lakes and rivers of that vicinity, several mysterious characters, among them figures representing cows, foxes, and more. The relic was later lost.

While the Dakota were greatly outnumbered, a significant number of Ojibwe held off from the engagement in the event their fellow men were to fall. This seemingly implies that during the battle, the numbers on both sides were relatively equal. Ojibwe agents later reported on behalf of their tribal leaders that only 34 of the warriors from their group fought at Shakopee; a number corroborated in subsequent written accounts of the battle from onlookers, such as the residents of Shakopee. While lives were claimed on both sides, no clear victor was established. Some accounts report that some of the Ojibwe men held back in fear of the conflict; one observer noted an Ojibwe warrior in the hollow of a tree during the skirmish, vocalizing and jumping.

After the fighting ceased, the Shakopee community speculated that the Ojibwe make another attempt on the Dakota tribe, as the long history of conflict between the two nations had shown a pattern of attacks and counter-attacks. Governor Henry Hastings Sibley decided that separating them was the only way to prevent this, and on June 2, he demanded that the Dakota still in the valley pack up their belongings and return to their reservation land. While there were rumors of both tribes assembling in the area for a second conflict, these were ultimately proved unsubstantiated.

The Battle of Shakopee is considered the final conflict between the Ojibwe and Dakota tribes, a long-lasting and bloody rivalry. A marker that once stood at the 1938 National Youth Administration overlook of U.S. Highway 212 stated "This was the last important battle between these tribes in Minnesota." Additionally, many of the land treaties between the Dakota and the United States government that put the two warring tribes in close proximity ultimately enraged the Dakota, and only four years after the Battle of Shakopee, Dakota gunfire rang out once more across Minnesota.
