Al-Bidya Mosque, also known as Al-Bidiyah or Al Badiyah, is a historical mosque in the Emirate of Fujairah, UAE.  This small square structure is estimated to date to the 15th century. The mosque is built from materials available in the area, primarily stones of various sizes and mud bricks coated in many layers of whitewashed plaster. The roof has four squats, helical domes that are supported by only one centrally placed pillar that also forms the ceiling. Entrance to the mosque is through double-winged wooden doors.

The prayer hall has a small mihrab, a simple pulpit, arches, and openings. A central pillar divides the internal space into four squares of similar dimensions. The pillar
supports all four domes that can be seen from the exterior. Inside the prayer hall, a number of small decorative windows allow light and air to enter the mosque. There are also cube-shaped spaces carved into the thick walls where copies of the Quran and other books are stored.

The mosque continues to host daily prayers, and is a tourist attraction.
