The 1834 Boston mayoral election saw the election of incumbent Theodore Lyman II. It was held on December 8, 1834.
Incumbent mayor Lyman was a Democrat.[1] Both the Democrats and the Whigs nominated Lyman, leaving him formally unopposed.[2] He was also supported by other tickets such as the "Grocer's Ticket".[3] The decision for the Whigs not to put forth their own candidate came despite their dominance in the city's other municipal races in coinciding election.[4]
