Alderwood is a neighbourhood in the city of Toronto, Ontario, Canada. It is in the western section of Toronto, formerly the city of Etobicoke. It is bounded by the Etobicoke Creek to the west, the Gardiner Expressway to the north, the CPR railway to the east and the CNR railway to the south.

Politically, Alderwood was part of the original Etobicoke township. The township subsequently became the Borough of Etobicoke and then City of Etobicoke. In 1998 the City of Etobicoke was merged with six other cities and the Metropolitan Toronto government to form an amalgamated City of Toronto. It is part of the Etobicoke-Lakeshore ridings at the provincial and federal level.

Alderwood is characterized by single family homes, many of which were constructed at the end of the second world war. Schools in the neighbourhood include Sir Adam Beck Junior School and Lanor Junior Middle School. The neighbourhood was formerly served by a high school (Alderwood Collegiate, later Father John Redmond Secondary School) but the school is vacant today. Another closed school Franklin Horner Junior Middle School is home to the Franklin Horner Community Centre.

The Alderwood Centre is a public complex that houses Sir Adam Beck Junior School, the Alderwood branch of Toronto Public Libraries, the Alderwood Action Afterschool child care centre and the Alderwood Pool, a 25-yard public pool.

The south west quadrant of the neighbourhood is zoned industrial and is home to manufacturing and warehousing businesses of various sizes. Among these is a Daimler-Chrysler casting plant.
