History
The First Baptist Church of Tampa was organized in 1859.
Churches began to meet in what was called the South Florida Baptist Association. The SFBA was organized in 1867, and held its first annual meeting in 1868.
Church members in the Hillsborough area began to see the need for their own association.
Perhaps it can be said that the Tampa Bay Baptist Association was born around noon, October 11, 1911, although there had been discussion and prayer before that date. The forty-fifth annual meeting of the South Florida Baptist Association was being held at Hopewell Baptist Church in Hillsborough County. There were 51 churches in the SFBA at this time and 19 of them withdrew to form the TBBA.  

As of 2014, the TBBA includes 150+ churches from Hillsborough and Pasco County.
