Wat Domnak is a famous Buddhist pagoda and one of the teaching monasteries in the city of Siem Reap, Cambodia.

Wat Damnak was formerly the royal residence of King Sisowath from 1904 to 1927. Later, the king’s palace was relocated near the Banana King Ashram. After the Royal Palace was relocated, the courtyard of the old palace complex was turned into a Buddhist pagoda.

During the Khmers Rouges regime, Wat Damnak was used by the Khmers Rouges as their military base. When the Khmer Rouges entered Siem Reap on 17 April 1975, the revolutionary committee was formed at Wat Damnak. The next day, Venerable Put Ponn and two other monks were escorted to attend a celebration in honour of their coup. The monks were required to say the traditional prayer celebrating victory.

Wat Domnak is one of the teaching monasteries of Siem Reap, and this academic ambition has developed considerably since the early 2000s.
