Gibson County is the northern third of the Evansville, Indiana–Kentucky Metropolitan Statistical Area.
Nearly 90% of the county exists within the Ohio River Valley American Viticultural Area along with all of neighboring Posey, Vanderburgh and Warrick counties and a portion of Pike County.
Despite being close to Evansville and experiencing a large growth of population in the central areas, Gibson County still remains a largely rural county with half of the ten townships having populations less than 2,000.
Less than 7 percent of the county's 500 square miles (1,300 km²) lies within incorporated settlements, or 10 percent if subdivisions are included.

The western part of the county consists largely of spread-out flood-prone farms with spotty marshes along the Wabash and White Rivers.
There are rolling hills around Owensville, and large forest and marshland tracts lie near the Gibson Generating Station and the three river settlements of Crawleyville, East Mount Carmel, and Skelton.
The northern part is near the White River and is more given to hills and forest.
The eastern part contains many hills and is also dotted with strip pits and active coal mines.
The southern part is more given to valley and marshland, drained by the Pigeon Creek which flows south through Evansville.

Even without Interstate 69, the county is within a day's drive of Chicago, Cincinnati, Chattanooga, Columbus, Indianapolis, Louisville, Memphis, Nashville, Springfield, St. Louis, even South Bend, and Fort Wayne despite the lack of freeway connection.
There are two major intersections in the southern extremes of the county.
One is the intersection of Interstate 64 and US 41.
The other is between Interstate 64 and Interstate 69, which will eventually link the county and Evansville to Indianapolis and Memphis and make a day trip to even Detroit possible.

The western half of the Patoka River National Wildlife Refuge and Management Area lies within Gibson County.

According to the 2010 census, the county has a total area of 499.16 square miles (1,292.8 km²), of which 487.49 square miles (1,262.6 km²) (or 97.66%) is land and 11.68 square miles (30.3 km²) (or 2.34%) is water.
