Monroe County is a county in the U.S. state of Indiana. In 1910 the US Census Bureau calculated the nation's mean population center to lie in Monroe County. The population was 137,974 at the 2010 United States Census. The county seat is Bloomington.
Monroe County is part of the Bloomington, Indiana, Metropolitan Statistical Area.
On July 4th, 2020, Monroe County was the scene of an attempted lynching of a black resident. Those responsible were never prosecuted.
According to the 2010 census, the county has a total area of 411.32 square miles (1,065.3 km2), of which 394.51 square miles (1,021.8 km2) (or 95.91%) is land and 16.81 square miles (43.5 km2) (or 4.09%) is water. The county terrain is low rolling hills, covered with vegetation and largely devoted to agricultural use or urban development. The eastern part is carved with drainages and gullies, leading to Griffy Lake. The county's highest point is McGuire Benchmark, just NW of Bloomington, at 994' (303m) ASL.
Bodies of water
Monroe County is divided between the basins of the East Fork and West Fork of Indiana's White River. The northern part drains to the West Fork; the southern part of the county drains to the East Fork, primarily via the Salt Creek and its tributaries, such as the Clear Creek (known as the "Jordan River" on Indiana University Bloomington campus).
Several artificial reservoirs have been constructed by damming the county's creeks. The largest is Lake Monroe, a large reservoir on the Salt Creek in the south-eastern part of the county. It is used both for recreational purposes and to supply the city with drinking water. Until the late 1960s, the main source of water supply was the smaller Lake Lemon (constructed 1953), in the northeastern part of the county; it is now the backup water source, and is mainly used for recreation.
The third largest is Griffy Lake, on the northern slope of the county. Constructed in 1924 by damming Griffy Creek, it was Bloomington's main water source until 1954; it is now used primarily for recreation although it also serves as an emergency water source. In 2012–2013, the lake was drained, the dam repaired, and the lake was refilled.
A smaller lake, Weimer (Wapehani) in the Clear Creek basin, was constructed for water supply purposes, but during most of its history was used purely for recreation - mainly fishing. In 2017 authorities revealed plans to drain this lake permanently, as it was considered to be unsafe. This was carried out in the summer of 2018.
Limestone has been quarried in Monroe County since 1826. A number of abandoned limestone quarries in the county are now cliff-surrounded lakes (as seen in the 1979 film Breaking Away), stable without ongoing human intervention.

For many years Monroe County was one of the most populous counties in the USA which did not contain any US highways or Interstate highways. However, in December 2015 the I-69 extension was completed into the county and this distinction disappeared. The highway was further extended north into Morgan County in 2018.
Although Monroe County has a rich railway history, currently its only railway is the Indiana Rail Road, whose mainline crosses the county from the north-east to the south-west, with branches to a few industrial facilities. There is no passenger service.
Between 1854 and 2004, an important north–south line connecting the Ohio River with Lake Michigan crossed Monroe County as well, serving Stinesville, Elletsville, Bloomington, Smithville, and Harrodsburg. It was operated by the Monon Railroad throughout much of the 20th century, and later by CSX. The last passenger service operating on this line was Amtrak's Floridian Chicago-Miami service, during 1972–1979. With the termination of this service in 1979, Monroe County lost passenger railway service. CSX continued to use this line for freight for another quarter of a century, but in 2004, it stopped using this line. Large parts of it have since been converted to trails.  
- Monroe County Airport, southwest of Bloomington. Scheduled passenger service to this airport was terminated ca. 1997, and since then the airport has been used by general aviation only.
