Pinoy Big Brother: Teen Edition 4 is the fourth teen edition of Pinoy Big Brother currently airing on ABS-CBN. The season started Easter Sunday, April 8, 2012. Toni Gonzaga, Bianca Gonzales and Robi Domingo reprised their roles as hosts, together with Pinoy Big Brother: Celebrity Edition 1 ex-housemate John Prats.
Auditions were held in major key cities in the Philippines and other parts of the world. A total of 22,305 people auditioned for the season. Fifteen housemates entered this season, nine on opening night and six on Day 2.
The House for this season remains largely unchanged since Unlimited, except for total redecoration spanning a week since the previous edition's finale. This marked the franchise's fastest House makeover. Visibly so far, there are only three areas of the House: the House itself, the garden, and the activity area. The House is decorated with a retro nostalgic theme, focusing on the 70's and 80's eras respectively.
Nine housemates, an all-male line-up plus female twins, entered the house on Day 1. Twins Jai and Joj were the first two to enter via the garden, hours before opening night to perform a secret task for Big Brother. The seven all-male housemates entered one by one on opening night. The second batch, an all-female line-up, entered on Day 2. The ages indicated were the housemates' ages upon their entrance to the House.
