The Beisan Subdistrict (Arabic: قضاء بيسان; Hebrew: נפת ביסאן) was one of the subdistricts of Mandatory Palestine.
It was located around the city of Baysan.
After the 1948 Arab-Israeli War, the subdistrict disintegrated; most of it became part of Israel, and has been merged with the neighboring Nazareth Subdistrict to from the modern-day Jezre'el County.
[citation needed] The southernmost parts, however, fell within the modern-day West Bank - because of that, they were first occupied and unilaterally annexed by Jordan, and were later occupied by Israel following the Six-day War.
