Wat Tha Mai is a Buddhist temple in Krathum Baen, Samut Sakhon, Thailand. It was known for sacred objects such as amulets and talismans. Many Thai celebrities visit this temple as part of their philanthropy and benefit from fortune telling by abbot Pra Ar Jan Uten Sirisaro. These activities have been criticized as commercialization of Buddhism. The temple is also well known in Thailand for placing its decals on rear windows of visitors' cars, producing more than 30,000 stickers each month.
