Magnet Mart was a Canberra-based chain of hardware stores that was locally owned and operated until 2011, when it was purchased by Woolworths.

At its peak it operated five large hardware stores and employed approximately 400 people around Canberra and southern New South Wales in Australia.

Magnet Mart formerly operated stores in Gungahlin, Phillip, Queanbeyan, Bowral and Goulburn.

In January 2008 advertising was relaunched, ditching "Magnet Mart Guy" for a couple and their neighbor, Gus.

In 2009 the "Magnet Mart Guy" returned to accompany the Start Smart slogan and has worked to reinforce the branding.
