Pinoy Big Brother: Teen Edition 1

Pinoy Big Brother: Teen Edition 1 began airing on April 23, 2006, three weeks after the end of the first Celebrity Edition. This is the third series overall in the franchise. It ran for 42 days and closely resembled the original show, unlike the relatively short Teen Big Brother, its British counterpart.

The theme song for this new edition was "Kabataang Pinoy" (Filipino Youth) by Itchyworms. The new theme song was first performed by the band during the first Celebrity Edition's finale on April 1, 2006.

Also, for one week, traffic lights and road signs were installed to teach the young housemates about helping their country in little ways by obeying traffic rules.

Kim Chiu won the first Pinoy Big Brother: Teen Edition.
