Yankton is a city in South Dakota, United States. It is the main city of Yankton County and became a city in 1889.
In 2020, about 15,411 people lived there. This made it the 7th largest city in South Dakota. Yankton is also the main city of the Yankton Micropolitan Statistical Area, which had about 23,297 people in 2021.
Yankton was the first capital of Dakota Territory. Its name comes from the Yankton tribe of Western Dakota people. The word I-hank-ton-wan in the Dakota means "the end village."
The city is located on the Missouri River. It is just below the Gavins Point Dam and Lewis and Clark Lake. The National Park Service has its main office for the Missouri National Recreational River in Yankton. The Human Services Center, a hospital for mental health, was started here in 1882. It is now on the National Register of Historic Places.
People often call Yankton the "River City." This is because it is close to the Missouri River. The river was very important for the city's early growth. Yankton is also known as the "Mother City of the Dakotas." This is because it played a big role in forming the Dakota Territory. This territory later became North and South Dakota.
Yankton also used to be called "Cement City." This was because it produced cement from Fort Hays Limestone. Some of this cement was even sent to help build the Panama Canal.

Where is Yankton Located?
Yankton is in southern South Dakota, right on the border with Nebraska. It sits on a special part of the Missouri River. This part of the river is one of the last natural, free-flowing sections. The U.S. National Park Service has named it the Missouri National Recreational River. This area stretches from Gavins Point Dam, west of Yankton, to Ponca State Park in Nebraska.
The city's main downtown area is on a natural landing along the Missouri River. To the west, the land rises to a high bluff called "Mount Marty." The Marne Creek also flows through the city and into the Missouri River.
The United States Census Bureau says Yankton covers about 8.45 square miles (21.9 square kilometers). Most of this is land, with a small part being water.
What is Yankton's Climate Like?

A Look at Yankton's History
Early Inhabitants and Explorers
Before European settlers arrived, the Yankton Sioux (Nakota) lived where Yankton is now. In 1804, the Lewis and Clark explorers visited the area. They met with the Yankton Sioux Tribe at a place now called Calumet Bluff.
In 1857, a Yankton Sioux village led by Chief Pa-le-ne-a-pa-pe ("Struck by the Ree") was at the city's current site. Two years later, the Yankton Treaty of 1858 opened the land for new settlers. The city started where a small creek, now called Marne Creek, flowed into the Missouri River. Yankton grew as a stop for steamboats. They would pick up fresh water and supplies, especially after gold was found in the Black Hills.
Yankton as Dakota Territory Capital
On March 2, 1861, President James Buchanan signed a law creating Dakota Territory. Yankton was chosen as the capital. President Abraham Lincoln then appointed William A. Jayne as the first governor. The first capitol building was a simple wooden structure. It was located at Fourth and Capitol Streets. The original building is gone, but a copy of it stands in Yankton's Riverside Park. Yankton was the capital until 1883, when it moved to Bismarck.
The Yankton Stockade
In 1862, there was a conflict in western Minnesota. Governor Jayne asked all men aged 18 to 50 in eastern Dakota to form groups to protect against possible attacks. In Yankton, a large stockade (a fort made of strong posts) was built. Settlers from nearby areas came to Yankton for safety. Although some groups of Native Americans came near Yankton, no attack happened. The stockade was later taken down. A monument now marks where it once stood.
Yankton College: A Place of Learning
In 1881, a group decided to start "Pilgrim College" in Yankton. This was to be the first private college in Dakota Territory. When it officially started, its name was changed to "Yankton College." Classes began in 1882. Yankton College was an important part of the city for over 100 years. However, it closed in 1983 due to money problems. The historic campus, which is on the National Register of Historic Places, was later bought by the Federal Bureau of Prisons. It is now a minimum-security prison called the Federal Prison Camp – Yankton.
River Port and the Great Flood of 1881
Yankton was a great place for steamboats to stop along the Missouri River. The first steamboat from St. Louis arrived in 1859. It brought goods and supplies to settlers and fur traders. The city grew even more after gold was found in the Black Hills in 1874. By 1880, Yankton was a busy riverboat port.
But on March 27, 1881, a huge ice jam on the Missouri River broke. Floodwaters and giant blocks of ice rushed towards the town. By March 29, the riverfront and downtown were covered in water, ice, and rocks. Several riverboats were destroyed. This flood, along with the growth of railroads, caused Yankton's riverboat traffic to slow down. The railroad had already reached Yankton in 1872. Over the next few years, Yankton's role as a major stop on the way west became less important.
In 1882, the Human Services Center was established as a hospital for mental health. On June 2, 1883, the capital of Dakota Territory was moved from Yankton to Bismarck.
