Keserwan District (Arabic: قضاء كسروان, transliteration: Qaḍā' Kisrawān) is a district (qadaa) in Keserwan-Jbeil Governorate, Lebanon, to the northeast of Lebanon's capital Beirut.

The capital, Jounieh, is overwhelmingly Maronite Christian.

The area is home to the Jabal Moussa Biosphere Reserve.

According to the medieval historian Gabriel ibn al-Qilai, the name “Kesrwan” derives from the Maronite muqadam Kisra of Baskinta.

[1] During the time of the Crusades, Keserwan was the northern frontier of the Kingdom of Jerusalem.
