Degaldoruwa Raja Maha Vihara (Sinhala: දෙගල්දෝරුව රජමහා විහාරය) is a Buddhist rock temple in Amunugama, Kandy, Sri Lanka.

[5] Following its completion, Rajasinghe placed it in the custody of a learned monk, Moratota Dhammakkanda Maha Nayaka Thera [1734-1811], who was also Rajasingha's teacher and chief advisor.

According to local folklore, the temple's origins relate to a time when a farmer investigated a gap between two large boulders near his village and discovered a pile of golden sickles.

The other members of the village became aware of this event and informed King Kirti Sri Rajasinha, who instructed them to clear the cave and erect a temple there.

[9][10] The finest painting is on the ceiling, ‘Mara Yudde’, an artistic depiction of Buddha's internal spiritual battle against Māra, the demon of death, rebirth and desire.
