The Military Demarcation Line (MDL), sometimes referred to as the Armistice Line, is the 154 mile-long land border or demarcation line between North Korea and South Korea. On either side of the line is the Korean Demilitarized Zone (DMZ). The MDL and DMZ were established by the Armistice at the end of the Korean War in 1953.

In the Yellow Sea, the two Koreas are divided by a de facto maritime "military demarcation line" and maritime boundary called the Northern Limit Line (NLL) drawn by the United Nations Command in 1953. The NLL is not described by the Korean Armistice Agreement.

The DMZ runs near the 38th parallel, covering roughly 248 kilometers.American and South Korean soldiers patrol this line along the South Korean side while North Korean soldiers patrol along the North Korean side.

In Korean, the line is called the Hyujeonseon (휴전선), meaning "armistice line." It is also sometimes called the Gunsa Bungye-seon (군사분계선), which literally means "military demarcation line." However, in colloquial usage, the dividing line is more often called the Sampalseon (삼팔선, "38th parallel"), a name likely coined at the end of World War II, when it would have been an accurate description of the North-South border.

The line itself is marked off by a series of 1,292 identical signs which are placed at intervals across the peninsula. The north facing side of the signs are written in Korean and Chinese, and in Korean and English on the south facing side. The signs are now aging and rusting.

There have been frequent skirmishes along the line since the armistice ended the fighting of the Korean War.
