KMJS Gabi ng Lagim (transl. Night of Terror) is an annual Halloween television special of GMA Network's news magazine show Kapuso Mo, Jessica Soho, featuring urban legends, horror, and supernatural stories from around the Philippines. It first aired on October 27, 2013, and has since been present annually, usually on the Sunday closest to Halloween and All Saints' Day, also known in the Philippines as Undás.^[1]

Kapuso Mo, Jessica Soho previously aired Halloween specials under different titles before GMA Public Affairs Assistant Vice President Lee Joseph Castel suggested in 2012 to create an annual special under one name. It later became the Gabi ng Lagim.^[2]

On each edition, the special features three to four real-life accounts with interviews with the actual people, actual photos, videos, and audios of the supernatural encounters, which made it one of the talked about shows in the Philippines during Halloween season online. In 2018, it was reported that the show generated 80,000 tweets in 3 hours.^[3][4]

Some stories featured on Gabi ng Lagim were made into full-feature films, including Sanib by Derick Cabrido from Gabi ng Lagim IV which was made into the film Clarita in 2019, and Junjun also by Cabrido from Gabi ng Lagim V, which was made into the film Sunod by Carlo Ledesma in 2019.^[2]
