Masjid Al Ghamamah, also known as the Mosque of the Clouds, is a historical mosque located in Medina, Saudi Arabia. This mosque is particularly associated with an event in the life of Prophet Muhammad (peace be upon him).

The mosque is situated near the Masjid al-Nabawi (the Prophet's Mosque) in Quba, a suburb of Medina. The name "Al Ghamamah" means "the cloud" in Arabic, and it is believed that the mosque earned this name because of an incident involving a cloud providing shade during one of the Prophet Muhammad's prayers.

According to Islamic tradition, the Prophet Muhammad once led the Eid prayer at a location in Quba, and during the prayer, a cloud appeared and provided shade to the Prophet and his companions. This event is considered significant, and the mosque was later built at the site to commemorate it.

Masjid Al Ghamamah has a distinctive large umbrella-like dome that is designed to resemble a cloud. The mosque's architecture reflects a combination of traditional and modern elements. One notable feature is the large retractable umbrella over the central courtyard, which can be opened and closed to provide shade as needed.

Pilgrims and visitors to Medina often include Masjid Al Ghamamah in their itinerary as part of their religious and historical tour, especially during the Hajj and Umrah seasons. It is a site of historical and religious importance in Islam.
