[2][3] The barangay acquired its original name, Bagong Bayan, which means "new town" in Tagalog, upon its establishment.

Its first lumang bayan (barangay head) was Cererina San Juan, and the primary jobs of the people then were fishing and farming.

Though it was the latest town that was founded then, the citizens of Taguig trusted the following people to be its councilors: Elino Cruz, Benito Garcia, Cerilo P. Santos, Arsenio Javier, Jose Aquino, Francisco dela Rosa, Francisco Tortosa, Claudio Marcelo and Rufino Dacumos.

Because of this, the government ordered the construction of what was then called the South Superhighway, leading to an increase in land purchases by corporations.

[4] Bagumbayan is bounded on the north by Lower Bicutan and Central Bicutan, to the east by Laguna de Bay, to the south by Bagumbayan River and Sucat in Muntinlupa, and on the west by the Philippine National Railways tracks and barangays North Daang Hari, Tanyag, and South Daang Hari.
