The Shiva Mandir Deobaloda, also known as the Mahadev Temple, is an ancient temple dedicated to Lord Shiva, located in Deobaloda, near Raipur, Chhattisgarh. Built during the 13th century by the Kalchuri dynasty, this temple is a protected monument under the Archaeological Survey of India.

The temple is known for its Nagara-style architecture and features intricate carvings and sculptures depicting various deities and mythological scenes. One unique aspect of the temple is that it is said to have been constructed in just six months, which is why it is also called the "Chhamasi Mandir" or "Six-Month Temple".

The temple has a Garbhagriha (sanctum sanctorum) housing a Shiva Linga, and a Navaranga Mandapa (hall) with beautifully carved pillars. The temple also has a Kund (sacred pond) and is believed to be connected to another old town, Arang, through a tunnel.
