Palm Valley is a census-designated place (CDP) in St. Johns County, Florida, United States.

Long before the first Spanish settlers arrived, there was an Indian village in what is known as Palm Valley today.

Early Franciscan missionaries constructed a mission in the area called The Nativity of Our Lady of Tolomato.

By 1739, Great Britain and Spain were at war and trouble was brewing for the Diego Plains settlers.

After Oglethorpe’s failure to capture St. Augustine, the Spanish military abandoned Fort San Diego, but other inhabitants moved into the area, living off the land and the cattle.

This intracoastal canal made access to the valley much easier for the residents that had settled in this area.

In addition to raising cattle, they farmed, logged, and sold palm fronds to religious groups.

The abundant water supply and deep woods areas in the valley were ideal for the concealment of illegal whiskey distilling.

Today most farms in the valley have disappeared, opening the land for luxurious residences overlooking the Intracoastal Waterway.

These include Palm Valley Landing, Plantation Oaks, Seaside, Odom's Mill, Dolphin's cove, and part of Sawgrass between A1A and the intracoastal.
