Plimmerton is a seaside suburb that lies in the northwest part of the city of Porirua in New Zealand, adjacent to some of the city's more congenial beaches. State Highway 59 and the North Island Main Trunk railway line pass just east of the main shopping and residential area.

Plimmerton has its modern origins as a late 19th century seaside resort. It is named after John Plimmer, an English settler and entrepreneur who, through the Wellington and Manawatu Railway Company, helped to fund and direct construction of the railway line. The estimated population is 2,130 as of June 2025.
