Freedom Ship is a floating city project initially proposed in the late 1990s by engineer Norman Nixon.

[1][2] The namesake of the project reflects the designer's vision of a mobile ocean colony, such that it is free from the property, municipal, or federal laws of any nation states.

The Freedom Ship project envisioned an integrated city 1,800 metres (5,900 ft) long[3] with condominium housing for 80,000 people,[3] a hospital, school system, hotel, casino, commercial and office occupancies, duty-free shopping and other facilities, large enough to require rapid transit.

Other projects, such as the ResidenSea, have similarly attempted to create mobile communities, though they have conservatively limited themselves to the constraints of conventional shipbuilding.

In regard to the economic flexibility and "freedom" created by such mobile settlements, these projects could be considered a realization of the avant-garde Walking City[5] concept from 1964, by British architect Ron Herron of the group Archigram.
