The Bartlett Arboretum is a private fifteen acre park in rural Belle Plaine, Kansas, that evolved in early 20th century from a recreational park and conservation area to an arboretum with formal gardens and experimental plots and nurseries.

The arboretum largely reflects the influences of professional landscape architect and horticulturist Glenn Bartlett, his wife and floral expert Margaret Bartlett, and Glenn's father who first purchased the property in 1910 to be used as a public athletic field for the small community and as a natural reserve complete with water fowl and non-indigenous trees.

After years of being under maintained, the Bartlett Arboretum is currently being restored with the goal for it to serve as an educational and events space.
