Al-Wustho Mangkunegaran Mosque is a historic mosque located in the Central Javanese city of Surakarta, to the west of the Mangkunegaran Palace. The mosque is one of the three oldest mosques of Surakarta. Al-Wustho Mangkunegaran Mosque was inaugurated as a state mosque ("masjid nagara") of the Mangkunegaran Palace.
