The Penang Floating Mosque (Malay: Masjid Terapung Pulau Pinang), also known as Tanjong Bungah Floating Mosque (Malay: Masjid Terapung Tanjong Bungah) is a mosque within the city of George Town in the Malaysian state of Penang.

A small mosque was first built at Tanjong Bungah in 1967 and it was expanded in In 1977 so that it may accommodate 500 worshipers. With increasing population, it soon became too small for the local Muslim community, but with limited land to expand, an idea was then proposed to build the mosque on the sea.

Although it is called a floating mosque, the mosque is actually built on stilts, only at high tide would it have the appearance of floating on water. It is built in a mix of Middle Eastern and local architectural style and features a prominent minaret. The mosque can accommodate 1,500 worshipers.
