Canopus or Canobus was an Ancient Egyptian coastal town, located in the Nile Delta. Its site is in the eastern outskirts of modern-day Alexandria, around 25 kilometres from the centre of that city.

Canopus was located on the western bank at the mouth of the westernmost branch of the Delta – known as the Canopic or Heracleotic branch. It belonged to the seventh Egyptian Nome, known as 'Menelaites', and later as 'Canopites', after it.
