The Boston mayoral election of 1855 saw the election of Alexander H. Rice. It was held on December 10, 1855.
Alexander H. Rice was nominated by a committee of citizens without a party label. Originally a Whig, at the time, Rice was avoiding associating himself with party organizations. The "Citizen's" slate he ran on performed well in Boston's coinciding City Council elections. Nathaniel B. Shurtleff was nominated by the "American Party" (the Know Nothings).
