Wat Khao Kaeo Worawihan is a second-class royal Buddhist temple of the Worawihan type located on a low hill in Sao Hai Subdistrict, Sao Hai District, Saraburi Province, Thailand. Originally built in the Ayutthaya period and later restored, it is notable for its hilltop ubosot, historic chedi, and revered Buddha images. The temple serves as an important religious and cultural center for the local community and retains Ayutthaya and Rattanakosin architectural elements.

The grounds include the main ordination hall, viharn, historic pagodas, Buddha images, and shaded courtyard areas. The setting is quiet and active for daily worship, with monks present and local devotees making merit. Areas to explore include the hilltop terrace, lower temple buildings, and landscaped grounds.

Originally founded as Wat Khao Kaeo in the Ayutthaya period, the temple has undergone several restorations in the Rattanakosin period and was later elevated to a second-class royal temple of the Worawihan type. It preserves architectural elements from the Ayutthaya era and reflects continued royal patronage and restoration.

As a royal temple and principal Buddhist institution of Sao Hai District, it serves as a center for religious observance, merit-making, and traditional festivals for the local community and is respected for its enshrined Buddha images.
