Pinoy Big Brother: Teen Edition 4 is the fourth teen edition and the tenth series overall of Pinoy Big Brother. The show premiered on Easter Sunday, April 8, 2012 almost a week after the Unlimited season concluded, and ended on July 7, 2012, lasting for 13 weeks, making it the longest teen edition yet. Toni Gonzaga, Bianca Gonzales and Robi Domingo reprised their roles as hosts. They are joined by Pinoy Big Brother: Celebrity Edition 1 ex-housemate John Prats.
Myrtle Sarrosa of Barotac Nuevo, Iloilo emerged as the winner of the season.
2-in-1 Housemates - Two housemates who are related biologically or by other means, are joined as one competing housemate, assigned by Big Brother. The status of one would be the status of the other. On Day 71, a split of connections was cast, in which both of the twins survived. Their shared status remained for the rest of the season.
House Players - They enter the house to test the remaining official housemates through tasks set by Big Brother and the audience.
Power of One - The public may only vote once per day per mobile phone number.
Big Jump to the Big Night - Remaining housemates compete to have a sure slot in the finals.
SE Voting System - The public is given the chance to vote to save or evict a housemate. The housemate with the lowest net votes, Save and Evict votes combined, is evicted. The system is to be used in the season finale.
The House featured only one house. The first time to do so since Celebrity Edition 2. This season used Unlimited's Luxury House with the same floor plan, 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 five areas of the House: the House itself, the garden, the activity area, a secret hallway leading into Big Brother's Time Machine, and Big Brother's Conference Room. The House is decorated with various items from on the 1970s and 1980s, such as old vinyl records on the walls which Big Brother said that it was inspired by his own teenage life.
