In Australia, an Avenue of Honour is a memorial avenue of trees, with each tree symbolising a person. The tradition, which originated in the Goldfields region of Victoria, Australia, is an important part of Australian culture. There are 547 known avenues of honour in Australia, in all states and territories except the Northern Territory. Over half are in Victoria.

In landscaping, an avenue, alameda, or allée, is traditionally a straight path or road with a line of trees or large shrubs running along each side, which is used, as its Latin source venire indicates, to emphasize the "coming to," or arrival at a landscape or architectural feature. In most cases, the trees planted in an avenue will be all of the same species or cultivar, so as to give uniform appearance along the full length of the avenue.
