The 1879 Eastern Maori by-election was a by-election held on 7 July in the Eastern Maori electorate during the 6th New Zealand Parliament.
The by-election was caused by the death on 24 February of the incumbent MP Karaitiana Takamoana.
The by-election was won by Henare Tomoana.
Henare Matua was seen by some as the "Government candidate" and a leader of the "Repudiation" faction.
