Sinagra is an outer northern suburb of Perth, Western Australia, located within the City of Wanneroo.
This suburb, formerly part of the suburb of Wanneroo, is named after the Sinagra family, migrants from Italy who arrived in the Wanneroo area in the 1920s. The City of Wanneroo established a sister city relationship with Sinagra, Sicily as a large number of families migrated from there to make a new home in Wanneroo.
Sam Sinagra owned a shop in Wanneroo, and the family were prominent citizens. The suburb name was approved on 3 April 1995.
