Portokalia Maleme (part of the Washington Navel variety) are sweet and juicy oranges of medium size, traditionally cultivated in the coastal zone of Chania Regional Unit, in Crete.

Their cultivation began during the 1920s and can be found in many varieties while their exceptional taste is related to the microclimate of Chania area (atmospheric humidity, sunlight during the whole year and abundant water available from irrigation of the White Mountains). They time of harvest begins in October and lasts until the end of May.

Portokalia Maleme were certified as PDO product (Protected Designation of Origin) in 1996, and they are the only Greek citrus fruit under this distinction.
