Varadaraja Perumal Devasthanam is a Vaishnavite temple dedicated to Lord Vishnu (in the form of Varadaraja Perumal), situated in the Mithila region of Bihar. This temple is notable for its South Indian architectural influences, which is a rare sight in northern Bihar. The temple stands as a remarkable testament to the pan-Indian spread of Vaishnavite worship and the cultural connections that have existed between different regions of India for centuries.

The temple reflects centuries-old cultural and religious connections between South India and the Mithila region, believed to have been established during periods of Brahmin migration and cultural exchange. Lord Varadaraja is a form of Lord Vishnu worshipped predominantly in Tamil Nadu — the famous Varadaraja Perumal Temple in Kanchipuram being one of the 108 Divya Desams (sacred Vaishnavite shrines). This Bihar counterpart speaks to the deep and enduring influence of Vaishnavite traditions across the Indian subcontinent.

The temple attracts devotees from across the region and is an important pilgrimage site for the Vaishnava community. Major festivals celebrated at the temple include Vaikuntha Ekadashi and other Vishnu-related observances such as Janmashtami and Ram Navami. During these festivals, the temple comes alive with elaborate decorations, special prayers, and religious discourses that draw visitors from surrounding districts.

The temple provides a unique cultural experience in the predominantly Shaivite landscape of Mithila, where Lord Shiva temples are far more common. The presence of this Vaishnavite shrine enriches the religious diversity of the region and offers visitors an opportunity to experience the distinct traditions of Vishnu worship. The temple is accessible from Simrahi via local roads, with the 40 km journey taking approximately one hour by taxi or private vehicle.
