新港（法语：Porto-Novo，又译新港）是西部非洲国家贝宁的首都，人口26万，不过其仅为该国名义上的首都，贝国的实际行政中心位于科多努（Cotonou）。

Porto-Novo (also known as Hogbonou and Adjacé) is the capital of Benin, and was the capital of French Dahomey. The commune covers an area of 110 square kilometres (42 sq mi) and as of 2002 had a population of 223,552 people.

It was originally developed as a port for the slave trade, an important part of many European Empires at the time including the Portuguese Empire.
