Wat Kudi Dao () is a restored Buddhist temple located in the eastern area of Ayutthaya, Thailand, outside the main city island. It represents a significant example of Late Ayutthaya architecture and is historically linked to the Ban Phlu Luang dynasty.
While the exact date of its original foundation is unclear, the temple underwent a major restoration in 1711 by King Thai Sa. The restoration project was supervised by the King's younger brother, Prince Boromakot (who served as the Front Palace), while the King himself simultaneously restored the nearby Wat Maheyong.
According to royal chronicles, the temple served as the residence of Phra Thep Muni (commonly known as Luang Pu Thuat), a high-ranking monk who acted as a spiritual advisor to Prince Boromakot. During the prince's stay at the temple to oversee construction, the site became a center for political gathering. It was here that negotiations concerning the royal succession took place, eventually leading to Boromakot's ascension to the throne.
Following the fall of Ayutthaya in 1767, the temple was abandoned and fell into ruin. In modern times, the Fine Arts Department has partially restored the site, stabilizing the structures for archaeological study and tourism.
The temple complex displays classic characteristics of the Late Ayutthaya style, noted for its elegance and the integration of foreign artistic influences.
