Bateshwar Sthan ( Sanskrit: बटेश्वर स्थान ) is an ancient site related to the Vedic sage Brahmarshi Vashishtha at Kahalgaon in Bhagalpur district of Bihar, India.

[1][2] It is believed as the Taposthali ( penance place ) of the sage Vashishtha where he established Shivlinga known as Bateshwar Nath Mahadeva.

The temple is at foothills of Bateshwar mountain on the bank of the north flowing Ganga located ten kilometres away from Kahalgaon.

Then Devashree Narada and Vishvakarma searched three places, they were Bateshwar Sthan of Kahalgaon, Chitabhumi of Devgarh in Jharkhand, and Varanasi of Uttar Pradesh.

According to the Vangiya Kayastha Kul Panchika, during the reign of the Sen rulers of Bengal, Ballala Sena came here and worshipped the Shiva lingam on the occasion of declaring his father-in-law Vata Krishna Mitra as the king of Magadha.
