Chad Errol Ramirez Booc (April 17, 1994 — February 24, 2022) was a Filipino volunteer Lumad teacher. He was known as an activist vocal on-ground and in social media. According to the AFP he was one of those killed in a supposed encounter between the NPA and the AFP on February 24, 2022, a claim that is disputed by loved ones and a forensic pathologist. Instead, they term the event as the 'New Bataan massacre'.
