Willaston is a northern suburb 39 kilometres (24 mi) northeast of the Adelaide city centre in South Australia.

The village may have been named after Willaston in Cheshire, due to a probable association with the Stocks family.

The Willaston General Cemetery is in the north of the suburb, alongside the retirement village.

Clonlea Park is located on Murray Road along the banks of the North Para River.

Willaston is also serviced by Main North Road, linking the suburb to Gawler.
