Deerfield Beach's history dates to 1890, when a small settlement named Hillsborough was developed along the Hillsboro River.

As the population grew to 20 by 1898, the settlement was now served by its own post office and the town was named Deerfield for the deer that grazed along the river.

By the early 20th century, as the town's population continued to grow, the Florida East Coast Railroad constructed tracks en route to Miami bisecting Deerfield.

Deerfield's early settlers were mostly farmers who grew pineapples, tomatoes, green beans, squash and fished along the Intracoastal Waterway.
