Allison Park was named for William O. Allison (1849–1924), the first mayor of Englewood Cliffs and a leader in preserving Palisades lands. Allison once had an estate here (some of the buildings from his estate are still standing, though the main house burned in 1903).

The Sisters of St. Joseph of Peace and St. Peter’s College (the school’s main campus is in Jersey City) own the property just north of Allison Park — the only private property along the Palisades summit from Fort Lee to the New York state line.
