Wat Roi Phraphutthabaht Phu Manorom is a Buddhist temple located on a hilltop in Mukdahan. The temple features a large Muk-coloured, i.e. pearl white, Buddha image seated in the bhumisparsa pose. Its main attraction, however, is a giant statue of a 120 meter long naga known as Phaya Sri Mukda Mahamuni Nihl Palanakaraat (fig.).

Besides this, the hilltop temple offers a panoramic view of the area, including Mukdahan Town, the Mekhong River with the Second Thai–Lao Friendship Bridge, and the Laotian town of Savannakhet.
