Jang Hang-jun (; born September 17, 1969) is a South Korean film director and television director, and also screenwriter in both fields. He is also professor at the Department of Theater and Film at Digital Seoul Culture Arts University. He made his directional debut in the 2002 film Break Out. Jang has directed the feature films Spring Breeze (2003), Forgotten (2017), Rebound (2023), and The King's Warden (2026).
In 2011, he turned to the small screen, co-wrote and directed Sign, a medical crime investigation drama starring Park Shin-yang and Kim Ah-joong.
Jang was born in Daegu in 1969. He grew up in a privileged household provided with a personal driver and subject-specific tutors. Despite these advantages, Jang did not prioritize his studies, choosing instead to spend his time socializing with friends. This lifestyle changed during his second year of high school when his father's construction business went bankrupt. Following this shift in circumstances, Jang enrolled in a theater department in Seoul. During his studies, he discovered a deep passion for the arts and began to seriously evaluate his professional strengths.
After graduating, Jang secured a position as the youngest writer at a broadcasting station, an opportunity facilitated by a senior acquaintance. His role shifted unexpectedly after six months when the lead writer disappeared. In a surprising turn of events, a script Jang had previously written was adopted by the station, resulting in his promotion to Field Director.
While working as a writer for the SBS entertainment department on the show Good Friends, Jang found inspiration in his friend Jang Jin's success in the Spring Literary Contest. This achievement motivated him to transition from television entertainment to the film industry. He began focusing on screenwriting and gained significant recognition in 1996 with his script for The Adventure of Mrs. Park, which effectively launched his cinematic career.
In 2026, he wrote and directed the historical film The King's Warden. The film was released on February 4, 2026, coinciding with the Korean New Year holiday. It received positive reviews and did well at the box office.
On March 4, 2022, Jang donated 30 million won to the Children's Fund in Ukraine, along with his wife Kim Eun-hee, to help Ukrainian victims in Russian invasion.
Jang married Kim Eun-hee in 1998. They have a daughter named Jang Yeon-soo.
