New Port is a north-western suburb of Adelaide, South Australia. It is located in the City of Port Adelaide Enfield.

In 2004, Premier of South Australia Mike Rann, announced the commencement of a major redevelopment of the Port Adelaide waterfront. With an estimated budget of $1.2 billion, the Newport Quays development was to include 2000 homes across six different precincts. At completion, the development was proposed to also include cafes, museums, public parks and various commercial properties. In 2007, the suburb of New Port was created from parts of the suburbs of Birkenhead, Ethelton, Glanville and Semaphore Park. The name "Newport Quays" had been requested but this was not supported by the relevant government authority. On 6 August 2009, the eastern boundary of the suburb was extended in part to the centre-line of the Port River.

By 2007, stage one of Newport Quays was complete, with stage two construction well underway. Ambitious new plans for stage three of the development were revealed in September 2007, including an apartment building constructed over the Port River. However, these plans never eventuated, and the New Port Quays development had ultimately been stalled.

Newport Quays received a lot of criticism from the local community for being unsympathetic to the local area and destroying local heritage. A state government established committee found many issues with plans for development stage 2B, including lack of open space, and exceeding of permitted building heights. In 2008, residents in New Port raised concerns that the new development was a "ghost town". The local council estimated that less than half of finished properties were occupied. Similarly, investors launched legal action as the resale value of properties in the developments had significantly dropped below the initial cost. No new developments took place in New Port following stage two. In 2011, Premier, Jay Weatherill officially cancelled the Newport Quays project. The state government was accused of shelving the project to win voters in a local by-election. The government indicated that it instead had planned to develop a new masterplan for the remaining vacant sites of the Newport Quays development.

Following eight years of stalled development, Renewal SA announced that the remaining land in New Port would be developed by Cedar Woods Properties. Under the proposal, Cedar Woods will construct up to 500 new townhomes and apartments across the north-west corner of New Port adjacent to Glanville railway station, and Fletcher's Slip, on the site of the former Holden factory.

Much like it's predecessor, the Fletcher's Slip development has not been without criticism. Members of the local community accused Cedar Woods of destroying local heritage that they had previously indicated would remain part of the development. A dilapitated warehouse on the north-west of the site, referred to as Shed 26, was demolished in 2019 after an extended protest campaign.

In July 2022, the first new residents moved into the first stage of the Fletcher's Slip development.

New Port is primarily bound by the Port River and the Outer Harbor railway line. The northern side of the suburb is bound by Semaphore Road and Nelson Street.
