Arcadia Pen and Arcadia Mountain are in Trelawny, Jamaica and were probably associated: it was common for Estates to have a "bush" area where they would plant provisions. Arcadia was originally a classical Greek name meaning a sort of paradisiacal place (?).

Arcadia Mountain came into the possession of the Commonwealth Missionary Society who sold it to Kaiser Bauxite Co in 1954.
The name "Arcadia" is found in four other locations in Jamaica:
