Nattawat Jirochtikul

Fourth Nattawat Jirochtikul is a Thai actor and singer whose nickname stems from his birth on the 200th anniversary of King Rama IV's birthday. He launched his entertainment career by winning GMMTV's "Thailand School Star 2019" competition, one of two victors in the contest. He completed his secondary education at Saint Gabriel's College through the grade twelve equivalency examination and is presently enrolled in Chulalongkorn University's Faculty of Law.

Fourth's on-screen debut came in 2021 with the series "F4 Thailand: Boys Over Flowers." His performance in "Moonlight Chicken" earned him the Outstanding Rising Star accolade at the Komchadluek Awards in May 2024. In December 2022, he released his first single—a collaborative cover of "Yak Rong Dang Dang" (อยากร้องดังดัง) for the "My School President" soundtrack, the series in which he took on his first lead role. A few months later, he issued his debut original solo track, "Let Me Tell You" (พูดได้ไหม), also tied to the series. Following several releases through GMMTV Records, he joined Riser Music in 2024, debuting under the label with "เทคะแนน (Candidate)" on February 20, 2024. Beyond performing, Fourth also runs his own clothing brand, 'NU MO NE'.
