The fourth season of the reality game show Pinoy Big Brother: Teen Edition premiered on the ABS-CBN network on April 8, 2012 and ran for 91 days until July 7, 2012. This season surpassed Teen Edition Plus' record of the longest edition of the series by 13 days.
This was the last separate season of this edition to air after all editions were merged into one season starting on Pinoy Big Brother: All In. This was also the first and only season in the series to date where the two-in-one housemates survived a split connection.
Myrtle Sarrosa of Barotac Nuevo, Iloilo emerged as the winner of the season. Karen Reyes was the runner-up, while Roy Requejo and Joj & Jai Agpangan were the finalists.
