Roatán, located between the islands of Útila and Guanaja ( 16°23′N 86°25′W16.38°N 86.42°W), is the largest of Honduras' Bay Islands. The island was formerly known as Ruatan and Rattan.

It is approximately 60 kilometers (37 mi) long, and less than 8 kilometers (5.0 mi) wide at its widest point.

In 2008, Princess Cruises announced they will be offering Western Caribbean Cruises to Roatán on the Crown Princess starting in the Fall of 2009, while Carnival Cruise Lines, Costa Cruises, Royal Caribbean, and Norwegian Cruise Lines already offer cruises to the island.
