The Indiana Uplands or the Hoosier Uplands are a geographical region in south-central Indiana. On a topographical map the Indiana Uplands begin slightly north of the city of Martinsville, Indiana and continue south to the Ohio River. The description of the region inspired the name of Upland Brewing Company. The region's approximate boundaries are Interstate 65 to the east and U.S. Route 231 to the west.

Nearly all of these hills are composed of sandstone, limestone, and siltstone from West to east. The siltstone hills are the most rugged followed by the sandstone while the limestone are the smoothest. This is contrast to the Tipton Till Plain immediately to the north in central Indiana, which features flat to gently rolling landscape.

Interstates 64 and 69 pass through this rugged section of the state with sections of both cut deep into the rock and others towering over the treetops. Overall, the Indiana Uplands have the same basic characteristics of the Pennyrile Region and the Highland Rim and are the northernmost extent of the range.
