The Cheramaan Perumal Juma Mosque (Malayalam: ചേരമാൻ ജുമാ മസ്ജിദ്) (Arabic: مسجد الرئيس جمعة) is a mosque in Methala, Kodungallur, Thrissur in the Indian state of Kerala. A legend claims that it was built in 629 CE, which makes it the oldest convert mosque in the Indian subcontinent which is still in use. It was built on the orders of the successor of Cheraman Perumal, the Chera King of modern-day Kerala. The mosque was constructed in Kerala style with hanging lamps, making the historicity of its date claims more convincing.
