1819
Yes. One of the provisions of the Adams-Onis Treaty of 1819 is the cession of Florida to the United States by Spain.
The Florida Cession, which refers to the transfer of Florida from Spain to the United States in 1819, encompasses approximately 72,000 square miles. This area includes both the Florida peninsula and the panhandle. The cession was formalized in the Adams-Onís Treaty, which established the boundaries of Florida and defined its territory as part of the U.S.
Spain ceded Florida to the US in 1819 when James Monroe was President. I am not aware that James Madison had anything to do with the transfer.

The Florida cession, formalized in the Adams-Onís Treaty of 1819, resulted in the United States acquiring Florida from Spain, significantly expanding its territory. This acquisition helped eliminate Spanish influence in North America and resolved border disputes, which strengthened U.S. claims to the southern territories. Additionally, the cession facilitated westward expansion and contributed to the growing sense of American nationalism during the early 19th century. Ultimately, it set the stage for future territorial acquisitions and conflicts in the evolving United States.

The French was the previous owner of British Cession. The United States purchased the western half of the Mississippi basin from France.
Florida became a territory of the United States in 1819.
Somehow, it became a US territory after John Quincy Adams signed the Florida Purchase treaty in 1819. Afterwards, the US began to occupy the State after closing on the deal with Spain for $5 million.
