Davendra Singh (born 1950) was a Fiji Indian small businessman and politician who came into prominence when he challenged and defeated the official National Federation Party (NFP) candidate in a by-election in March 1985.
The Lautoka Indian Communal seat became vacant in April 1984 following the resignation of the former leader of the NFP, Jai Ram Reddy.
Koya did not go ahead with his threat to resign but challenged the results in the Supreme Court of Fiji, which confirmed Singh's election.
The election result triggered a series of events which led to the decline of the NFP and the rise of the Fiji Labour Party (FLP).
For a while, Singh sat as an independent member in the House of Representatives, but in September 1985 he attempted to merge the NFP Youth Wing with the newly formed Fiji Labour Party, which the FLP refused because it would not allow group affiliation.
