The Nebraska Territory, including this county, was opened for settlement through the Kansas–Nebraska Act on May 30, 1854. Richardson County was created that same year and reorganized in 1855 by the first territorial legislature.  It was named after William A. Richardson, a US Representative from the state of Illinois who had sponsored the Kansas-Nebraska Act; subsequently, in 1858, Richardson was appointed governor of the Nebraska Territory. 
The first courthouse was built in 1863. The second courthouse was built in 1873 and burned on May 7, 1919.

Richardson County lies at the SE tip of Nebraska. Its east boundary line abuts the west boundary line of the state of Missouri (across the Missouri River). Its south boundary line abuts the north boundary line of the state of Kansas. Several branches and tributaries of the Big Nemaha River flow southeast through the county, depositing their waters into the Missouri River at the county's SE corner. The county's terrain consists of rolling hills, sloped to the southeast, cut by numerous drainages. The county area is largely devoted to agriculture.  The lowest point in the state of Nebraska is located on the Missouri River in Richardson County, where it flows out of Nebraska and into Kansas and Missouri.
The county has a total area of 555 square miles (1,440 km2), of which 552 square miles (1,430 km2) is land and 2.7 square miles (7.0 km2) (0.5%) is water.
