Daviess County (/ˈdeɪvɪs/ "Davis"), is a county in Kentucky. As of the 2020 census, the population was 103,312. Its county seat is Owensboro. The county was formed from part of Ohio County on January 14, 1815.

Daviess County is included in the Owensboro, KY Metropolitan Statistical Area. Daviess County also shares its namesake with another nearby Daviess County of Indiana. Both counties are in the Illinois-Indiana-Kentucky Tri-State Area.

Daviess County was established in 1815. The county is named for Major Joseph Hamilton Daveiss (a recording error in the State Clerk's office accounts for the error in spelling, which was never corrected), the United States Attorney who unsuccessfully prosecuted Aaron Burr. The county's borders were altered in 1829 to form Hancock County, in 1830 to absorb a small area surrounding Whitesville, in 1854 to cede land to McLean County, and finally in 1860 to annex 44 square miles (110 km) from Henderson County.

The courthouse was burned in January 1865 during the American Civil War, but the county records were spared destruction because they had been transferred to a church.

According to the United States Census Bureau, the county has a total area of 477 square miles (1,240 km), of which 458 square miles (1,190 km) is land and 18 square miles (47 km) (3.8%) is water. The northern half of the county along the Ohio River is relatively flat, with a few rolling hills dotting the landscape. The southern portion is mostly rolling hills mixed with flat valleys. The southern portion was mined for coal in the past, especially in the rolling hills along Panther Creek and other streams.

Daviess County has long had a reputation as the leading center of the production of distilled spirits, chiefly Kentucky bourbon. Walter McFarland, who moved here from North Carolina, began making whiskey and peach brandy in about 1804 on a 200-acre (0.81 km) estate just south of Panther Creek, on today's U.S. 431. Cornelius Westerfield also began distilling corn whiskey in the early 1800s on his farm three miles (4.8 km) southwest of Whitesville, Kentucky, on Deserter Creek. It finally closed in 1872, after more than 60 years of production.

By the 1880s, 18 large distilleries operated in Daviess County at the same time. Today only three remain. One dates back to 1869, the former Glenmore Distillery Company, which was originally the R. Monarch Distillery. In 1885, J.W. McCullough began the Green River Distillery which ran until Prohibition and was subsequently purchased thereafter by Charles Medley Distillers where it ran until the 1950s, changing ownership a number of times without producing anything until its eventual purchase by Trinidad-based Angostura Limited, who bought the Medley Distillery in 2007 with plans to make its entrance into the world's bourbon market, but the severe global recession in 2008 ended those plans. The distillery was sold to the Terressentia Corporation in 2014. In 2020, the distillery was renamed as Green River Distilling Co, restoring the Green River name that was used at the facility under McCulloch's original ownership.

The southwestern portion of the county around the Panther Creek area was heavily mined through the 1960s till the early 1990s. After 1998 large tracts of mined land were left unclaimed. Then after a lengthy search for contractors by the state government's Division of Abandoned Mine Lands, work commenced on the largest tract, a 42-acre (170,000 m) tract once part of the now defunct Green Coal Company. The 42 acres (170,000 m) of unclaimed land were part of Green Coal Company's mine once known as the "Panther Surface Mine". Green Coal Company was a staple mining company in Daviess County and was based nearby in Henderson.

Reclamation work commenced at the site on November 8, 1999, and was completed April 14, 2000. The licensed blaster employed by the contractor blasted the highwall into the pit, resulting in a reduced effort to grade and dress the final slope. Enough topsoil was gained from the area above the highwall to allow a growing medium for re-vegetation purposes. Through innovative field techniques and extraordinary cooperation from the contractor, this site has been returned to a very safe, stable and productive property. All 42 acres (170,000 m) of this project was reclaimed expending $127,538.82 of the available bond. The land is now safe for the public and is considered prime farm property once again.
