Clarence Square is a small park in downtown Toronto, Ontario, Canada, where Wellington Street West meets Spadina Avenue.

The origins of the name of the square are unclear, but both are linked to members of the British Royal Family, Prince William Henry or Albert Victor, Duke of Clarence with the former being the likely name as the name appeared on maps in the 1850s.

In 1854, he was a participant in the Charge of the Light Brigade at Balaclava, saving the lives of two fellow soldiers.

Today, however, industry has left the neighbourhood and the area is primarily residential and commercial.
