No connection really, although some Baptist Christians have sought to see a connection. Baptists, as a recognized entity, go back to the early 1600s. They often describe themselves as a "New Testament" church because of their emphasis on two ordinances (or sacraments), the use of immersion in baptism, and simplicity of their church and church leadership structure (things they hold in common with churches of the 1st century).
John the Baptist was a Jewish prophet who carried out immersion baptism (like the Baptists). However, it was pre-Christian rite that it marked a radical repentance. Within the Christian context, baptism is a formal and public association of oneself with Christ, His death, and His resurrection.
