The Jacksonville Jumbo Shrimp are a Minor League Baseball team of the International League (IL) and the Triple-A affiliate of the Miami Marlins. They are located in Jacksonville, Florida, and are named for shrimp caught in the area. The team plays their home games at 121 Financial Ballpark, which opened in 2003. They previously played at Sam W. Wolfson Baseball Park from 1962 until the end of the 2002 season.

A team known as the Jacksonville Suns competed in the Triple-A International League from 1962 to 1968. The franchise was relocated to Norfolk, Virginia, as the Tidewater Tides in 1969. After one season without professional baseball, a different Suns team came to the city in 1970 as members of the Double-A Southern League (SL). From 1985 to 1990, the team was known as the Jacksonville Expos during an affiliation with the Montreal Expos, but they returned to the Suns moniker in 1991. The club rebranded as the Jacksonville Jumbo Shrimp before the 2017 season. In conjunction with Major League Baseball's reorganization of Minor League Baseball in 2021, the Jumbo Shrimp were elevated to the Triple-A East, which was renamed the International League in 2022.

Jacksonville won their only IL championship in 1968 as the Triple-A affiliate of the New York Mets. They won the SL championship six times. The first came in 1996 as the Double-A affiliate of the Detroit Tigers. As a farm club for the Los Angeles Dodgers, they won in 2001 and 2005. Three SL titles were won as the Double-A affiliate of the Miami Marlins, including back-to-back championships in 2009 and 2010 and most recently in 2014.
