Cottrell Key is an island in the Florida Keys in Monroe County, Florida, United States. It is within the boundaries of the Key West National Wildlife Refuge.[1]
Located in the Outlying Islands of the Florida Keys, it is the northernmost of the Mule Keys that are 9 miles (15 km) west of Key West.[2]
It is named for Captain Jeremiah Cottrell,[3] who was the captain of a lightship that was anchored at the key in the early 19th century.[4]
