Ellerslie Road is a major arterial road in south Edmonton, Alberta, Canada. Before the City of Edmonton expanded this far south, it was rural grid road Township Road 514, earning the nickname Ellerslie Road. When the city was numbering its streets, it was found that this road laid south of Quadrant (1) Avenue, and so the city adopted a quadrant system, naming it 9 Avenue SW, however Ellerslie Road has remained the preferred name by Edmontonians.
