Ahiyari is a village in the Jale block of Darbhanga district, Bihar, close to Kamtaul railway station. It is the site of Ahalya Sthan, the temple traditionally identified with the Ramayana episode in which Ahalya — wife of the sage Gautama, cursed to become stone — is released from the curse by the touch of Lord Rama. The site is counted among the earliest Ram-Janaki temples of the region.
The present temple is said to have been built in the 17th century under the Khandavala (Darbhanga Raj) rulers Maharaja Chhatra Singh and Maharaja Rudra Singh. It stands within the old Gautam-ashram tradition of Mithila and is closely tied to the Sita–Rama legends that pervade the area around Janakpur and Sitamarhi.
Large fairs gather here every year at Ram Navami and at Vivah Panchami, when Mithila celebrates the marriage of Rama and Sita. The everyday language is Maithili, and the shrine is a long-standing stop on the Ramayana pilgrim circuit of north Bihar.
