Qasriga Nahāvand () wuxuu ahaa qalcad qadiimi ah oo ka soo jeeda Sasanian Persia oo ku taal waxa hadda ah magaalada Nahavand ee gobolka Hamedan, Iran. Burburkii qalcaddan ee Dagaalkii Nahavand
waxay ahayd carwadii ugu waynayd ee soo martay guushii ay Muslimiintu ka gaareen Faaris. Si kastaba ha noqotee, qalcaddu way sii jirtay ilaa waqtigii Naser al-Din Shah Qajar. Waxaa la sheegay in Naser al-Din Shah uu helay khasnad markii uu qodayay qanad. Kadib wuxuu amray in qalcadda la burburiyo si loo helo khasnado badan; si kastaba ha noqotee, wax badan lama helin.
