The 1840 Chicago mayoral election saw Democratic nominee Alexander Loyd defeat incumbent Whig Benjamin Wright Raymond by a landslide 15.8 point margin.
With a narrative that local elections such as Chicago's would be a bellwether of the coming 1840 United States presidential election, both parties locally viewed the election as being of great importance.

The election was held on March 3. [2]
