'Mosque of the Tree'), also known as Masjid Dhu al-Hulayfah (Arabic: مَسْجِد ذُو ٱلْحُلَيْفَة), is a miqat and mosque in Abyār ʿAlī, Medina, Saudi Arabia.

The miqat mosque is located west of Wadi al-'Aqiq, where the final Islamic prophet, Muhammad, entered the state of ihram before performing 'Umrah, after the Treaty of Hudaybiyyah.

[1][unreliable source] The mosque is located 7 km (4.3 miles) SW of the Al-Masjid an-Nabawi and was defined by Muhammad as the miqat for those willing to perform the Hajj or Umrah pilgrimages from Medina.

It consists of two sets of galleries separated by a wide yard of approximately 1,000 m2 (11,000 sq ft).

One of the mosque's minarets stands distinct from the others, square at the bottom but round at the top in a diagonal shape, rising to a height of 64 metres (210 ft).
