The Port River (officially known as the Port Adelaide River) is part of a tidal estuary located north of the Adelaide city centre in the Australian state of South Australia. It has been used as a shipping channel since the beginning of European settlement of South Australia in 1836, when Colonel Light selected the site to use as a port. Before colonisation, the Port River region and the estuary area were known as Yerta Bulti (or Yertabulti) by the Kaurna people, and used extensively as a source of food and plant materials to fashion artefacts used in daily life.
The Port River dolphins are a popular tourist attraction.
