Eagan's northern border is mostly along Interstate 494. Its southern border is about a mile south of Cliff Road. Its eastern border runs mostly along Minnesota State Highway 3.

The city's influence in the region grew when Northwest Airlines (now Delta Air Lines) and Thomson West (now Thomson Reuters) established their headquarters there.
