Arthur Airport is not a widely recognized term in major encyclopedic sources. No prominent international, national, or regional airport is commonly known by this exact name. The phrase may be used informally or locally to refer to small municipal or private airfields situated in communities named Arthur, such as:
- Arthur Municipal Airport – a public‑use airport identified by the FAA identifier K1A7, located near Arthur, North Dakota, United States. It serves general aviation and is owned by the city of Arthur.
- Arthur Airport (Canada) – a possible reference to a private or regional airstrip in a locality named Arthur within Canada, though no verifiable public records confirm its existence.
Because reliable, comprehensive references to a singular, notable "Arthur Airport" are lacking, the term does not meet the criteria for an established encyclopedic entry. The name likely derives from the place name “Arthur,” which itself can originate from the given name Arthur of Celtic origin meaning “bear king.”
