The Farewell Sermon (Arabic: خطبة الوداع, Khuṭbatu l-Widāʿ ) also known as Muhammad's Final Sermon or the Last Sermon, is a religious speech, delivered by the Islamic prophet Muhammad on Friday the 9th of Dhu al-Hijjah, 10 AH (6 March 632) in the Uranah valley of Mount Arafat, during the Islamic pilgrimage of Hajj.

Muhammad al-Bukhari refers to the sermon and quotes part of it in his Sahih al-Bukhari. Part of it is also present in Sahih Muslim and Sunan Abu Dawood. Verse 5:3, "Today I have perfected for you your religion ...", is believed to have been recited during the address as the capstone verse of the Quran.

Various versions of the sermon have been published, including several English translations. The sermon consists of a series of general exhortations for Muslims to follow the teachings that Muhammad had set forth in the Quran and sunnah.
