Roberts County, South Dakota is located in the northeastern part of the state, near North Dakota. The area was originally inhabited by indigenous peoples, primarily members of the Sisseton Wahpeton Oyate tribe. In the 1860s, European settlers began moving into the region, prompted by the prospect of available farmland and the construction of the railroad in the nearby area.

The county was officially organized in 1883 and named after S.G. Roberts, a prominent politician in the Dakota Territory. The town of Sisseton was established as the county seat. In the early years, agriculture played a crucial role in the county's economy, with settlers primarily engaging in farming and cattle raising.

Over time, the county experienced growth and development. The completion of the Chicago, Milwaukee, St. Paul and Pacific Railroad in 1914 further boosted the local economy by improving transportation routes and connecting the area to larger markets. The county's population grew steadily during the early 20th century, with towns such as Summit and New Effington emerging as centers of commerce.

Like many rural areas in the United States, Roberts County faced challenges during the Great Depression and subsequent years. However, the county's agriculture-based economy remained resilient, and efforts to diversify the local economy eventually gained traction. Today, Roberts County is known for its beautiful natural landscapes, including several lakes and wildlife refuges, and it continues to be a vibrant agricultural community with a rich history.
