Patisia or Patissia is a neighbourhood of Athens, Greece. It is split in two neighbourhoods: Ano Patisia and Kato Patisia. The main streets of Patisia are Patision Av. and Acharnon Av.

Patision Street is one of the major streets in central Athens, Greece. Though it is known as Patision, its name for its stretch between Panepistimiou Street and Amerikis Square, was changed to 28 October Street, commemorating the day in 1940 that the Greek dictator Ioannis Metaxas refused the Italian dictator Benito Mussolini's ultimatum that Greece submit to Italian control, thus starting the Greco-Italian War.
