|Saek, Lao, Thai|
|Animism, Theravada Buddhism|
Most Saek cultural practices were either absorbed from the surrounding Lao and Thai cultures, or were practices common to the greater Tai ethnicity. However, the Saek are known for their round dances.
Most of the Saek in Laos adhere to their traditional beliefs, which include ancestor worship, with a small number adhering to Theravada Buddhism. Offerings are often made to spirits to prevent illness. Spirits often represent the forces of nature, and each Saek village typically has a guardian spirit.
