City of Paris was a British passenger liner operated by the Inman Line that established that a ship driven by a screw could match the speed of the paddlers on the Atlantic crossing.

Cunard quickly ordered two additional screw steamers to partner the paddlers Scotia and RMS Persia on the New York express route.

With City of Paris, Tod and Macgregor started construction of five fast liners for Inman's Liverpool - New York route to rival the Cunard Line's best.

Gibbs credits City of Paris herself with the Blue Riband for a November 1866 westbound voyage from Queenstown to New York at 13.75 knots.
