Eagan is a city in Dakota County, Minnesota, United States. The city is south of Saint Paul and lies on the south bank of the Minnesota River, upstream from the confluence with the Mississippi River. Eagan and nearby suburbs form the southern portion of Minneapolis–St. Paul. The population of Eagan was 64,206 at the 2010 census and currently ranks as Minnesota's 11th largest city. Currently the eighth largest Minnesota city and the fourth largest suburb in the metro area, Eagan is predominantly a commuter town of both Minneapolis and Saint Paul.

Originally a rural Irish farming community and "Onion Capital of the United States", Eagan became in the 2000 Census. The largest growth in Eagan took place following the relocation and expansion of Highway 77 along with the construction of the new six-lane bridge (with three northbound and three southbound lanes) over the Minnesota River in 1980 and also the completion of the final Interstate 35E freeway section southbound from Minnesota State Highway 110 in Mendota Heights to the area where it joins 35W in Burnsville in the mid-1980s. Its northern border is primarily along Interstate 494. Its southern border is about a mile south of Cliff Road. Its eastern border runs primarily along Minnesota State Highway 3. The western border runs primarily along the South bank of Minnesota River. The city's influence in the region grew when the companies Northwest Airlines (now Delta Air Lines) and Thomson West (now Thomson Reuters) established their headquarters.
