University of Nevada, Reno Arboretum, State arboretum on the University of Nevada campus in Reno, Nevada, US

The University of Nevada, Reno Arboretum is a state arboretum spread across the university campus in Reno, Nevada, established in 1985. It holds over 60 genera and about 200 species of trees, with several cultivars, plus shrubs, flowers and native flora. Named areas include the Cherry Blossom Garden, Jimmie's Garden, the Merriam A. Brown Rose Garden and the Joe Robertson Native Garden.

The University of Nevada, Reno Arboretum was established in 1985 as a state arboretum spanning the campus. Its Quad was first a parade ground for student cadets in the late 19th century, then replanted in 1908 to Thomas Jefferson's design for the University of Virginia lawn. Dutch elm disease forced the removal of several elms in 1988.

The arboretum's plantings carry names tied to donors and events: the Challenger Tree Memorial in Benson Gardens uses Blue Atlas Cedars to commemorate the astronauts lost in the 1986 Challenger accident, and the Merriam A. Brown Rose Garden is devoted to roses. The Joe Robertson Native Garden gathers plants of the Great Basin, Mojave and Sonoran deserts.

The arboretum is not a fenced site: its plantings are distributed across the UNR campus in Reno, so visitors walk between separate areas. The Quad, with its rows of elms, is the central landmark to start from. Manzanita Lake and the Joe Robertson Native Garden lie on the campus grounds.

The arboretum was established in 1985, the same year as its Las Vegas counterpart, and holds over 60 genera and about 200 species of trees, many with several cultivars. Thirty-six mature elms line the Quad, replanted in 1908 to Thomas Jefferson's design for the University of Virginia lawn.
