Nadi Open is a former electoral division of Fiji, one of 25 open constituencies that were elected by universal suffrage (the remaining 46 seats, called communal constituencies, were allocated by ethnicity). Established by the 1997 Constitution, it came into being in 1999 and was used for the parliamentary elections of 1999, 2001, and 2006. It was located in the western part of the main island of Viti Levu.

The 2013 Constitution promulgated by the Military-backed interim government abolished all constituencies and established a form of proportional representation, with the entire country voting as a single electorate.

In the following tables, the primary vote refers to first-preference votes cast. The final vote refers to the final tally after votes for low-polling candidates have been progressively redistributed to other candidates according to pre-arranged electoral agreements (see electoral fusion), which may be customized by the voters (see instant run-off voting).
