Avalon is a neighbourhood located in Ottawa, Ontario It is located in the east end of the city in Orleans.

This neighbourhood was non-existent until the late 1990s when the urban sprawl intensified in the east end. Avalon quickly developed in the area is now bordered to the north by Innes Road, to the east by Trim Road, the west by Tenth Line Road and to the south by the city's urban boundary which is moved further to the south by the years. Evidently, new homes and condos consisted most of the residential units in Avalon.

The development of the area slowed when the developer had to return to previously built houses to fix foundations. Some have criticized the builder for building on swampland without proper engineering.

At the intersection of Innes and Tenth Line, a large commercial zone with several department and big-box stores developed in conjunction of the residential boom of Avalon. This new district displaced some customers away from Place d'Orleans. A smaller commercial area is currently underway on Trim Road south of Innes.
