Ceiba is a small town in northeast Puerto Rico. It is named after the famous ceiba tree.

Ceiba, situated near Fajardo, used to be home of a American military air-base, the Roosevelt Roads Naval Station. The base has been abandoned, however, and governor Sila María Calderón has spoken about turning it into a major international airport, to serve as a relief to Luis Munoz Marin International Airport in San Juan, and to increase the number of international airlines that operate into Puerto Rico. She has been met with skepticism about these plans by such groups as environmentalists, economists and others, and the situation as far as what will be done with Ceiba's old air base is being debated.

Former IBF world Jr. Middleweight boxing champion Carlos Santos hails from Ceiba.
