Valparaiso is a city in Okaloosa County, Florida, United States. It is part of the Crestview–Fort Walton Beach–Destin, Florida Metropolitan Statistical Area. As of the 2020 census, the city population was 4,752, down from 5,036 at the 2010 census.

Valparaiso was named after Valparaiso, Indiana (which in turn, was named after Valparaiso, Chile) and is a twin city also with its neighboring city, Niceville. The name of the city is Spanish, and translates to "paradise vale" or "paradise valley".

Chicago businessman James E. Plew, who relocated to the Florida Panhandle of Northwest Florida in 1922, became "one of Northwest Florida's pioneer developers," and settled on Valparaiso "as the most likely spot for development.

In 1924, he founded the Bank of Valparaiso, constructed the Valparaiso Inn, organized the Chicago Country Club which constructed the Valparaiso Country Club golf course, and was instrumental in many other development activities in the community."

"Other interests of Mr. Plew included the founding of the Shalimar Winery, which was established to use the surplus grape crop of the county. He also founded the Valparaiso Novelty Company, helped to establish a knitting mill in the community and was interested in a number of other enterprises to which he made investments to help their development."

Plew thought that a military payroll would boost the depression-stricken economy of the region. He leased from the city of Valparaiso the Valparaiso Airport, an arrowhead-shaped parcel of 137 acres (0.55 km) cleared in 1933 as an airdrome.

In 1934, Plew offered the U.S. government 1,460 acres (6 km) contiguous land for a bombing and gunnery base. This leasehold became the headquarters for the Valparaiso Bombing and Gunnery Base activated on June 14, 1935, under the command of Captain Arnold H. Rich. This was the founding of Eglin Air Force Base. The field was assigned the ICAO airport code VPS for Valparaiso, which Destin-Fort Walton Beach Airport retains to this day. In Niceville, there is an elementary school named in his honor.

According to the United States Census Bureau, the city has a total area of 12.8 square miles (33 km), of which 11.9 square miles (31 km) is land and 0.8 square miles (2.1 km) (6.35%) is water.

Summers are usually somewhat wetter than winters, with much of the rainfall coming from convectional thunderstorm activity. The Köppen Climate Classification subtype for this climate is a humid subtropical climate zone (Cfa).
