Cassidy International Airport is an airport located north of Banana, a settlement on Kiritimati (also known as Christmas Island) in Kiribati. Until 2018, it was the only airport in the Kiribati part of the Line Islands with an IATA or ICAO code.

The airport is served by Fiji Airways from Nadi, Fiji and Honolulu, United States, but not during the COVID-19 pandemic and closure of international borders.
