Tocobaga (occasionally Tocopaca) was the name of a chiefdom, its chief, and its principal town during the 16th century. The chiefdom was centered around the northern end of Old Tampa Bay, the arm of Tampa Bay that extends between the present-day city of Tampa and northern Pinellas County. The exact location of the principal town is believed to be the archeological Safety Harbor site, which gives its name to the Safety Harbor culture, of which the Tocobaga are the most well-known group.
