What county is Palm Bay in — Palm Bay, Florida

Palm Bay, Florida is in Brevard County, where the U.S. Census Bureau lists it as an incorporated city and where it is the largest city by population.

The Census Bureau 2020 place codes file for Florida carries one line for the city: Palm Bay city, incorporated place, Brevard County FL (Census place codes). The City of Palm Bay places itself the same way, describing the city as located in south Brevard County, adjacent to the Indian River Lagoon, which is part of the Intracoastal Waterway (City of Palm Bay). No Florida county carries the Palm Bay name.

The common mix-up is with Palm Beach County, and the same Census file shows why the two do not overlap. It lists Palm Beach town and West Palm Beach city under Palm Beach County FL, a separate county (Census place codes). A Palm Bay address, a Palm Bay tax bill and a Palm Bay voter registration all run through Brevard County offices, not Palm Beach County ones. The names share a word and nothing else: Palm Bay took its name in 1925, when the 200 residents of a settlement called Tillman petitioned to rename their town (City of Palm Bay history).

Yes: ACS 2020-2024 estimates count 130,132 Palm Bay residents, about one in five of Brevard County's 632,780, well ahead of Melbourne at 86,576.

The Census Bureau's ACS 2020-2024 5-year profile for Palm Bay city gives a total population of 130,132 and a median age of 41.0 (ACS DP05, Palm Bay). The county profile for the same period gives Brevard County 632,780 residents and a median age of 46.7 (ACS DP05, Brevard County). Dividing the two population figures, 130,132 by 632,780, puts about 20.6 percent of Brevard residents inside Palm Bay city limits. Melbourne, the next city north, counts 86,576 residents in the same release (ACS DP05, Melbourne). Palm Bay is also younger than its county by almost six years of median age, 41.0 against 46.7.

Palm Bay has led the county for decades. The city's own timeline records that in 1990 Palm Bay became the most populous city in Brevard County with 62,632 residents, and that the population passed 100,000 in 2006 (City of Palm Bay history). The City of Palm Bay also describes the city as the largest incorporated area in Brevard County by territory (City of Palm Bay). The Tax Collector labels its branch in the city Palm Bay (South Brevard Co.) (Brevard County Tax Collector).

Three Brevard County elected offices, the Supervisor of Elections, the Clerk of the Circuit Court and the Tax Collector, share a Palm Bay address at 450 Cogan Drive SE.

The Supervisor of Elections lists four offices: Titusville at 400 South Street, Viera at 2725 Judge Fran Jamieson Way, Melbourne at 1515 Sarno Road, and Palm Bay at 450 Cogan Drive SE, Palm Bay, FL 32909 (Brevard County Supervisor of Elections). The Clerk of the Circuit Court and Comptroller lists a Palm Bay Office at 450 Cogan Dr. SE, closed between 11:30 AM and 1:30 PM, with its Viera Office at 2825 Judge Fran Jamieson Wy open 8:00 AM to 5:00 PM (Brevard County Clerk).

The Tax Collector's Palm Bay (South Brevard Co.) branch at the same address lists real estate taxes, auto tags, boats, hunting and fishing, driver licenses, business tax renewals, birth certificates, HAZMAT services and concealed weapon license services, 9:00 AM to 5:00 PM M-F (Brevard County Tax Collector). Palm Bay's own City Hall, a city office, is at 120 Malabar Road SE (City of Palm Bay). Last verified: October 11, 2026, on the Brevard County Tax Collector website.

No: Titusville, in north Brevard County, has been the county seat since 1879, according to the Florida Division of Historical Resources marker at the Historic Brevard County Courthouse.

The marker at 506 South Palm Avenue in Titusville states that Brevard County was founded in 1855 and Titusville became the county seat in 1879 (Historic Brevard County Courthouse marker). That choice was made 81 years before Palm Bay incorporated: the City of Palm Bay timeline dates incorporation to 1960, with 2,808 residents under Mayor Harry Pollak and the Town Council (City of Palm Bay history). The marker adds that the courthouse continues to serve Brevard County (Historic Brevard County Courthouse marker).

For a Palm Bay household the practical result is a split map. Elections and tag renewals can start at 450 Cogan Drive SE, while the Clerk also lists a Viera Office at 2825 Judge Fran Jamieson Wy and a Titusville Office at 400 South St. (Brevard County Clerk).

Brevard County's southern line follows the Sebastian Inlet centerline and the St. Sebastian River, and the Brevard communities of Malabar, Grant-Valkaria and Micco lie east and south of Palm Bay toward that line.

Section 7.05 of the Florida Statutes describes the county outline in survey language: from the thread of the St. Johns River east to the Atlantic Ocean, south along the coast to the centerline of the Sebastian Inlet, then to the mouth of the St. Sebastian River and along the thread of the St. Sebastian River and its south fork, before turning west and north back to the St. Johns (s. 7.05, Florida Statutes). The statute's history line opens with s. 1, Mar. 14, 1844 and lists ch. 651, 1855 among later acts, the same era the courthouse marker gives for Brevard's creation.

Palm Bay therefore sits in the south of Brevard County but not at its edge. The Census place codes file assigns Malabar town, Grant-Valkaria town and the Micco census designated place to Brevard County (Census place codes). The Census Gazetteer places the internal points of Malabar (27.987057 N, -80.58245 W) and Grant-Valkaria (27.934301 N, -80.565885 W) east of Palm Bay's -80.664962 W, and Micco's at 27.856377 N, south of Palm Bay's 27.954802 N (Census Gazetteer). In the south of the county the statute's western line is the line dividing ranges thirty-four and thirty-five east, and only further north does it follow the thread of the St. Johns River (s. 7.05, Florida Statutes).

Palm Bay's Brevard County roots go back to Tillman, settled in 1887 at the mouth of Turkey Creek and placed in Brevard County by a state marker describing it in 1914, before the 1925 renaming and the 1960 incorporation.

The City of Palm Bay timeline begins in 1887, when early homesteaders settled in a town called Tillman at the mouth of Turkey Creek (City of Palm Bay history). A state historical marker at 1422 Miller Street adds that by 1914 the Florida Indian River Catholic Colony had settled nearly 100 midwestern families around Tillman, on the banks of the Indian River and Turkey Creek, at a time when Brevard County did not have a resident Catholic priest (Florida historical marker). The parish members built St. Joseph's Church themselves, and Bishop Michael J. Curley dedicated it in 1914.

The marker calls St. Joseph's Church of Palm Bay the oldest Catholic church in continuous use in Brevard County. The National Park Service NPGallery record lists St. Joseph's Catholic Church on Miller St. NE, Palm Bay, Brevard County, under National Register ID 87000816, published 12/3/1987 (NPGallery).
