The 2016 Plebiscite on Democratic Renewal was a non-binding referendum held in the Canadian province of Prince Edward Island between October 27 - November 7, 2016. The referendum asked which of five voting systems residents would prefer to use in electing members to the Legislative Assembly of Prince Edward Island.

The referendum was conducted using Instant runoff voting, and no option was the choice of a majority in the first count. After three options were eliminated due to being un-electable, mixed member proportional representation received more than 52% support on the final count. But government ignored the result, holding another referendum in 2019.
