River gum refers to any large tree from the Eucalyptus genus that is commonly found growing along the banks of rivers, streams, or other water bodies.

The term "river gum" is more commonly used in Australia, while the name "river red gum" is often used in other English-speaking countries.
River gums are known for their remarkable resilience to water conditions and are frequently found in flood-prone areas. They have adapted to survive in fluctuating water levels and can tolerate periods of inundation as well as dry spells. This adaptability has made them an iconic feature of Australian river systems.
The tree typically grows to heights ranging from 20 to 50 meters, with a wide spreading canopy that provides shade and shelter to various wildlife. River gums have slender, smooth bark that peels away in long ribbons, revealing patchy patches of white and grey. Their leaves are usually silver-grey or bluish-green, tapering to a point, and emit a distinct eucalyptus scent.
River gums play a crucial ecological role in the Australian landscape. They provide habitat for numerous bird species, marsupials, and other wildlife, as well as support various aquatic organisms in the adjacent water bodies. Additionally, their deep-rooted systems help stabilize riverbanks, preventing erosion and maintaining water quality. Due to their aesthetic value and ecological significance, river gums are often planted in parks and gardens to recreate the natural beauty and diversity associated with Australian waterways.
The etymology of the word "river gum" can be traced back to its individual components.
The word "river" originates from the Old English word "rīfer", which itself comes from the Proto-Germanic word "*ribru" or "ripari", meaning "stream" or "riverbank". This word has remained relatively consistent across Indo-European languages, such as the Middle Dutch word "riviere" and the Old Norse word "fljōr" for "river".
The term "gum" refers to the tree, specifically the eucalyptus tree. "Gum" in this context is derived from the Middle English word "gome", which comes from the Old English word "gāma". In turn, "gāma" traces its roots back to the Proto-Germanic word "*gamô", meaning "rubber" or "resin".
