Sak Yant is a traditional form of Thai tattooing that has its roots in Thai culture and Buddhism. The term "Sak Yant" is derived from "Sak" which means to tattoo and "Yant" which refers to sacred geometrical designs or magical incantations. Sak Yant tattoos are deeply ingrained in Thai culture and are often associated with Buddhism and traditional Thai spiritual beliefs. The tattoos are believed to offer protection, blessings, and various magical or spiritual benefits.

Sak Yant tattoos typically feature intricate and symbolic designs, often based on ancient sacred geometrical patterns and Buddhist iconography. Each design has a specific meaning and is believed to possess particular powers, such as protection, luck, or strength. Many Sak Yant designs incorporate Buddhist prayers, Pali scripts, and images of Buddha or other Buddhist deities. Monks or traditional tattoo artists often perform the tattooing process, accompanied by specific rituals and chanting. The traditional method of creating Sak Yant tattoos involves using a bamboo stick or metal rod with a sharp needle, tapping it into the skin to insert the ink. This is in contrast to modern electric tattoo machines.
