Charles Philippe Hippolyte de Thierry (April 1793 – 8 July 1864) was a nineteenth-century adventurer who attempted to establish his own sovereign state in New Zealand in the years before the Treaty of Waitangi between the British Crown and the Māori chiefs in 1840.

Upon reaching England, his father Charles Antoine de Thierry, claimed the title of Baron Nasher.

De Thierry subsequently arranged a purchase of 40,000 acres (16,000 ha) at Hokianga, in Northland, through Kendall while at Cambridge.

In the Marquesas Islands, he announced himself King of Nuku Hiva[1] and wrote to James Busby, the British Resident in New Zealand, of his intentions to land there and establish himself as "sovereign chief".

[3] In Sydney 1837 he recruited some locals to join his adventure, but when he arrived in the Hokianga, rangatira (chiefs) Tāmati Wāka Nene and Eruera Maihi Patuone repudiated his claims.
