Pinoy Henyo High: Alumni Edition is an edition of the segment Pinoy Henyo that premiered on 14 November 2011 and continued until 24 March 2012.
Hundreds of pairs of alumni from various high schools across the Philippines face each other in the daily elimination round of the competition. They then undergo a series of elimination rounds before being narrowed down in the semi-finals. The contestants were further narrowed down into six pairs who competed in the grand finals of the competition.
The daily round of this edition follows the regular format and rules of the original Pinoy Henyo. The pair who correctly guesses the word with the fastest time advances to the jackpot round. In the jackpot round, the winning pair must take turns to correctly guess any three of the ten words provided in under three minutes.
The grand finals of the competition follows the core format of the jackpot game of a typical daily round. Every pair is given the same ten words from two categories. One player is assigned "Bagay", while the other player is assigned "Pagkain". Each pair must take turns to correctly guess the words from their own category as quickly as possible in under three minutes. Pairs can opt to pass, but they cannot return to those skipped words. The pair who guesses any three words with the fastest time wins the game.
The educational institutions who competed in the grand finals were Ramon Avanceña High School, Cabuyao National High School, Panghulo National High School, Meycauayan College, Novaliches High School, and Ismael Mathay Sr. High School.
Wilbur "Acoy" San Francisco and Phina Corral of Panghulo National High School were the winners of the competition after guessing three words within 2 minutes 8 seconds. They received ₱300,000 in cash prize and a trophy. Meanwhile, another ₱500,000 was given to their former high school to be used for scholarships, school supplies, and other school funding.
The winning pair then faced the other two grand winners of the 2011 Pinoy Henyo: Intercollegiate Edition and the 2011 Pamilyang Pinoy Henyo in a special edition titled Pinoy Henyo: Battle of the Champions. It was held on 31 March 2012.
