List of colonial governors of Florida
The colonial governors of Florida governed Florida during its colonial period (before 1821). The first European known to arrive there was Juan Ponce de León in 1513, but the governorship did not begin until 1565, when Pedro Menéndez de Avilés founded St. Augustine and was declared Governor and "Adelantado" of Florida. This district was subordinated to the Viceroyalty of New Spain. In 1763, following the transfer of Florida to Britain, the territory was divided into West Florida and East Florida, with separate governors. This division was maintained when Spain resumed control of Florida in 1783, and continued as provincial divisions with the Spanish Constitution of 1812. The Spanish transferred control of Florida to the United States in 1821, and the organized, incorporated Florida Territory was established on March 30, 1822. This became the modern State of Florida on March 3, 1845.

Spain ceded Florida to the United States in 1819 with the Adams–Onís Treaty, and the United States took possession in 1821. Effective government was slow in coming to Florida. General Andrew Jackson was appointed military governor in March 1821, but he did not arrive in Pensacola until July. He resigned the post in September and returned home in October, having spent just three months in Florida. His successor, William P. Duval, was not appointed until April 1822, and he left for an extended visit to his home in Kentucky before the end of the year. Other official positions in the territory had similar turn-over and absences.
