Greenwood is a suburb of Perth, Western Australia, located in the City of Joondalup. The suburb is located 18 km from Perth's central business district. It is bordered by the Mitchell Freeway, Hepburn ave, Wanneroo road and Warwick road.

The Gold Land Development Corporation used the name Greenwood Forest as the promotional name of the estate which commenced development in the area in 1969. The reserve between the suburbs of Duncraig and Greenwood was used for the construction of the Mitchell Freeway in 1985–1986.

Greenwood is home to a senior high school and three primary schools:

• Greenwood College
• Greenwood Primary School
• West Greenwood Primary School
• Liwara Catholic Primary School

The original Greenwood Primary School closed in 1997 and the land was sub-divided and sold as residential lots. During June 2007, the government announced that Allenswood Primary School and East Greenwood Primary schools would amalgamate, temporarily at the East Greenwood site, and a new school would be built on the Allenswood site. Allenswood primary closed at the end of the 2007 school year and was demolished, making way for the construction of the new school, expected to be completed in late 2009. In 2008, East Greenwood Primary School was renamed Greenwood Primary School, later relocating, at the commencement of Term 4 2010 to the newly constructed, ex Allenswood Primary Site. East Greenwood Primary was then also demolished.

Greenwood Senior High School became independent in 2011-2012 and changed its name to Greenwood College.
