The Fell Arboretum is an arboretum located across the campus of Illinois State University in Normal, Illinois.
The arboretum began in 1867 when Jesse W. Fell, the university's founder, obtained $3,000 from the state legislature for campus landscaping. He planted 1,740 trees on campus that year and 107 trees the following year. An enthusiastic tree planter, Fell wished the campus to contain every tree native to Illinois. In 1995 the campus was formally registered as an arboretum and named in Fell's honor.
