Lees Avenue is both a road and a neighbourhood in Ottawa, Canada. The area lies in the narrow stretch between the Rideau Canal and Rideau River south of Sandy Hill and the Queensway and is part of Old Ottawa East. The neighbourhood is dominated by five large apartment buildings, some of the largest in Ottawa. These buildings range from low cost to moderate cost and mostly house new immigrants, students and young professionals. Across the Rideau River to the east Hurdman is a more recently built such area.
