The Old Collier County Courthouse is a historic two-story concrete and stucco courthouse building located in Everglades City, Florida. Designed in the Classical Revival style, it was built in 1926 by Barron Collier, who developed Collier County and for whom the county was named. In 1962, the county seat was moved to East Naples and a new courthouse complex was built there. The building later served as the Everglades City Hall.
