The L-SAM (Long-range Surface-to-Air Missile; {{Korean |hangul=장거리 지대공 미사일 |rr=Janggeori Jidaegong Misail}}) is a South Korean long range surface-to-air missile developed by the Agency for Defense Development (ADD), Hanwha, and LIG Nex1. The performance levels are comparable to the American THAAD and the Israeli Arrow 2 and Arrow 3. L-SAM serves as a key system in South Korea's Korean Air and Missile Defense (KAMD).{{cite web|url=https://www.nknews.org/2025/01/south-korea-unveils-plans-for-new-missile-defense-system-to-counter-north-korea/|title=South Korea unveils plans for new missile defense system to counter North Korea|publisher=NK NEWS|date=14 January 2025|author=Joon Ha Park}}

The development of L-SAM Block 1 was officially completed in May 2024 and was declared fit for combat by the Defense Acquisition Program Administration (DAPA).
