Te Hapuku (died 1878), sometimes known as Te Ika-nui-o-te-moana, was a Māori leader of the Ngāti Te Whatuiāpiti hapū of the Ngāti Kahungunu iwi in Hawke's Bay, New Zealand, and a farmer and assessor.
In 1838 Te Hapuku visited the Bay of Islands where he signed the 1835 Declaration of the Independence of New Zealand.
From the 1850s he was a keen seller of land, wishing to attract the economic benefit of European settlers.
He now rests in the Urupa in Te Hauke with a cenotaph donated by the New Zealand Government.
