Rio is a small place in Martin County, Florida, United States. It is called an "unincorporated community" because it doesn't have its own city government. It's also a "census-designated place" (CDP), which means the U.S. Census Bureau counts its population separately.
In 2020, about 980 people lived in Rio. If you visit, you'll hear locals say its name like "Rye-oh." Rio is part of the larger Port St. Lucie area, which is a big group of cities and towns connected by jobs and daily life.
History of Rio: How It Started
Rio has an interesting past, especially with its post office.
Early Beginnings of Rio
The area was first planned out as "Rio St. Lucie" in 1893. That same year, a post office opened on March 24, but it was named "Rio San Lucie."
Changes to the Post Office Name
Later, on December 1, 1897, the post office name was made shorter to just "Rio." However, this post office closed down on March 15, 1902. Mail for the area then went through the post office in Goslingville. Goslingville was located on a narrow piece of land just north of where the Roosevelt Bridge is today.
Reopening and Final Change
The Rio post office reopened on April 6, 1904. It stayed open until October 15, 1927. After that, its services were moved to the post office in Jensen, which is now known as Jensen Beach.
