Carlos, also known as Calos or King Calusa (died 1567), was king or paramount chief of the Calusa people of Southwest Florida from about 1556 until his death. As his father, the preceding king, was also known as Carlos, he is sometimes called Carlos II. Carlos ruled over one of the most powerful and prosperous chiefdoms in the region at the time, controlling the coastal areas of southwest Florida and wielding influence throughout the southern peninsula. Contemporary Europeans recognized him as the most powerful chief in Florida.
