The 2015 St Peter Port North by-election was held in the States of Guernsey district of St Peter Port North on 2 December 2015 following the death of deputy Martin Storey in July 2015.
3,224 residents were eligible to vote, a reduction to 86% of those who had been eligible for the 2012 election. There was some controversy over holding a by-election as the cost is estimated at £51,100 to elect someone to sit as a deputy for just five months, especially when the number of deputies and therefore seats will be reduced in April 2016.
There were three by-election candidates, Mike Henderson, David Noakes, and Charles Parkinson. There were 3,220 registered voters and the turnout was 883 (27%). Parkinson won with 571 votes, Henderson received 184, and Noakes 109.
