University of Hawaii at Hilo Botanical Gardens, Educational botanical garden at University of Hawaii campus in Hilo, United States.

The University of Hawaii at Hilo Botanical Gardens occupy a windward, rain-fed site on the Hilo campus at 485 W Lanikaula St. The grounds hold one of Hawaii's largest cycad collections, with 126 species from Africa, China, North and Central America and Australia, alongside an international palm collection and all five Big Island Pritchardia species.

The gardens were established in the 1980s by Professor Don Hemmes, who began the project after a student asked about pine trees. What started as a simple educational idea grew into a substantial plant collection.

The gardens began with a student's remark to professor Don Hemmes about never having seen a pine tree, which led him to plant the first trees on the Hilo campus in the 1980s. The living collections also serve as working material for several university faculties, including the pharmacy faculty.

The gardens are located on campus between the Science Building and the Hale Kehau Dining Hall along Lanikaula Street. A campus parking pass is needed to visit.

The collection includes over one hundred cycad species, with forty Zamia varieties originating from Mexico, Central America, and South America. This diversity makes it one of the largest cycad collections in Hawaii.
