Blue Springs is a city in Jackson County, in the U.S. state of Missouri. Blue Springs is located 19 miles (31 km) east of Kansas City. It is the 8th largest city in the Kansas City metropolitan area and 10th largest city in the state of Missouri. As of the 2020 census, the population was 58,604.

The city's history is tied to the migration of settlers seeking their fortunes out west during the age of manifest destiny. Pioneers found the area to be an ideal stopover due to the abundance of clean water from the local spring. The presence of water and a need for supplies led to the construction of a grist mill and a permanent settlement; now the site, on NW Woods Chapel Road, of Burrus Old Mill Park.

An early settler, Franklin Smith, arrived in Blue Springs from Virginia in 1838 and became a leading figure in the community's development. He established the first post office in 1845, naming it after the well-known springs.

The settlement continued to grow near the springs until March 1878, when the Chicago and Alton Railroad announced plans to build a station about one mile east of the original settlement. To take advantage of the commerce the railroad would bring, the town moved its center to the site of the new station and continued its development as a rural trading center. The Chicago & Alton Hotel built in 1878 is the oldest business in the city.

The Jackson County Court granted the incorporation of Blue Springs on September 7, 1880, making it the fourth settlement in the county to be incorporated.
