The Soltani Mosque of Borujerd is a large mosque in the centre of Borujerd, in the province of Lorestan, western Iran.
The edifice was built in the Qajar period atop the ruins of an older mosque, which had been probably built in the 10th century AD. Soltani means "related to Sultan," and likely refers to Fath Ali Shah Qajar, who ordered this building to be rebuilt.
The stone inscription on the surface of its western portico bear the date 1248 AH, and on the wooden door opening on Ja’fari Avenue, the date 1291 AH can be read.
