Manggahan High School (Mataas na Paaralan ng Manggahan, formerly "Rizal High School Annex-Manggahan") is a public high school in Karangalan Village, Brgy. Manggahan, Pasig City.

ANRRENN
The site of Manggahan High School was once a private drug rehabilitation center called Anti-Narcotics Research and Reformation Network (ANRRENN). It was reported that the center was operating illegally and the National Housing Authority owned the lot. Because of these complaints, the operation of the center stopped and the NHA donated the lot to the city government of Pasig.
