James Alfred Nash, known as Jimmy Nash, was a Reform Party Member of Parliament in New Zealand and a Mayor of Palmerston North.

The mayor of Palmerston North is the head of the municipal government of Palmerston North, New Zealand, and presides over the Palmerston North City Council. The current mayor is Grant Smith, who became mayor in a February 2015 by-election. This resulted from the resignation of Jono Naylor in October 2014 after his election to the House of Representatives. Since the 2013 election, Palmerston North is one of the few councils that uses the single transferable vote electoral system for the election of mayor.
