Dubois County (/duːˈbɔɪz/ doo-BOYZ) is a county located in the U.S. state of Indiana. As of 2020, the population was 43,637. The county seat is Jasper. Dubois County is now the sole county of the Jasper Micropolitan Statistical Area.

Dubois County was formed on December 20, 1818, from Orange, Pike and Perry counties. It is named for Toussaint Dubois, a Frenchman who fought in the American Revolutionary War, the Battle of Tippecanoe and the War of 1812. Dubois was a merchant who lived mainly in Vincennes. He drowned in 1816 while crossing the Little Wabash River near Lawrenceville, Illinois.

In 1818, as many as half of the residents of the county died of milk sickness. The plant contains the potent toxin temetrol, which is passed through the milk. The migrants from the East were unfamiliar with the Midwestern plant and its effects.

Dubois County switched to the Central Time Zone on April 2, 2006, and returned to the Eastern Time Zone on November 4, 2007; both changes were controversial as Huntingburg wished to remain on Central Time while Jasper never wanted to leave Eastern Time.

The original county seat was Portersville. In 1830, the county seat was moved south to Jasper.

According to the 2010 census, the county has a total area of 435.33 square miles (1,127.5 km), of which 427.27 square miles (1,106.6 km) (or 98.15%) is land and 8.06 square miles (20.9 km) (or 1.85%) is water.

The county government is a constitutional body, and is granted specific powers by the Constitution of Indiana, and by the Indiana Code.

County Council: The county council is the legislative branch of the county government and controls all the spending and revenue collection in the county. Representatives are elected from county districts. The council members serve four-year terms. They are responsible for setting salaries, the annual budget, and special spending. The council also has limited authority to impose local taxes, in the form of an income and property tax that is subject to state level approval, excise taxes, and service taxes.

Board of Commissioners: The executive body of the county is made of a board of commissioners. The commissioners are elected county-wide, in staggered terms, and each serves a four-year term. One of the commissioners, typically the most senior, serves as president. The commissioners are charged with executing the acts legislated by the council, collecting revenue, and managing the day-to-day functions of the county government.

Court: The county maintains a small claims court that can handle some civil cases. The judge on the court is elected to a term of four years and must be a member of the Indiana Bar Association. The judge is assisted by a constable who is also elected to a four-year term. In some cases, court decisions can be appealed to the state level circuit court.

County Officials: The county has several other elected offices, including sheriff, coroner, auditor, treasurer, recorder, surveyor, and circuit court clerk. Each of these elected officers serves a term of four years and oversees a different part of county government. Members elected to county government positions are required to declare party affiliations and to be residents of the county.

Dubois County is part of Indiana's 8th congressional district and is represented in Congress by Republican Larry Bucshon. It is also part of Indiana Senate districts 47 and 48, and Indiana House of Representatives districts 63, 73 and 74.
