Phillip Darrell Duppa (October 9, 1832 – January 30, 1892) was a pioneer in the settlement of Arizona prior to its statehood.

He told John G. Bourke that he had been born at Marseilles and that his family served in the diplomatic service.

He is buried at the small Pioneer and Military Memorial Park a few blocks from the state Capitol.

Phoenix was founded in 1868 and incorporated in 1881, and the name proposed by Duppa came from the story of the mythical Phoenix's rebirth from the ashes, the basis being the rebirth of a city of canals that was rebuilt on the site of the ancient Hohokam canal systems that dated back to about 700–1400 AD.

[2] Duppa founded New River, north of Phoenix, as a stagecoach stop.
