Possum or Opossum: Quick Answer
Opossum is the correct name for the marsupial native to North and South America, including the well-known Virginia opossum.
Possum refers to separate marsupial species found mainly in Australia, New Guinea, and surrounding areas.
Simple rule:
- United States or Canada → Opossum
- Australia or New Zealand → Possum
The Origin of Possum or Opossum
The word opossum comes from the Powhatan (Algonquian) word apasum, meaning white animal. English settlers adopted the term in the 17th century when describing the unfamiliar marsupial they encountered in the Americas.
Over time, everyday speech shortened opossum to possum. When Europeans later discovered similar-looking animals in Australia, the shortened word stuck but for an entirely different group of marsupials.
That shared linguistic history is the root of today’s confusion.
