The Arrakkal Museum is a museum dedicated to the Arakkal family, the only Muslim royal family in Kerala, south India. The museum is actually a section of the Arakkalkettu (Arakkal Palace). The durbar hall section of the palace has been converted into a museum by the Government of Kerala. It was opened in July 2005 after a Rs. 9,000,000 renovation.

Arakkal Kettu was the residence of the former Arakkal Ali Rajas, the only Muslim royal family of Kerala. Protected by the Archaeological and Tourism Department, this palace complex is today a museum. The Arakkal Kettu Museum houses a splendid display of numerous artefacts and heirlooms belonging to the Rajas. The musuem is closed on Mondays.
