Key Largo is the first and longest Key, 33 miles long, in the island chain of the Florida Keys. We are the northernmost island of the Florida Keys connected to the mainland by one primary route - US Highway 1 and one bridge - Jewfish Creek Bridge.

Once called Rock Harbor, but renamed after the popular 1948 movie Key Largo starring Humphrey Bogart and Lauren Bacall. A portion of the movie was filmed in Key Largo.
