Mungyeong Saejae (Hangul: 문경새재) is a mountain pass in central South Korea. It lies on Joryeong Mountain between the main peak (1017 m) and Sinseon Peak (967 m). The pass itself rises to above sea level. Mungyeong Saejae connects Mungyeong City, North Gyeongsang province with Goesan County in North Chungcheong province. Water flowing down from the Mungyeong side of the pass eventually flows into the Nakdong River and meets the Sea of Japan at Busan. Runoff from the Goesan side eventually flows into the Han River, which passes through Seoul to meet the Yellow Sea at Incheon.
