Wat Traimit Witthayaram Worawihan (Thai: วัดไตรมิตรวิทยาราม วรวิหาร) is a Theravada Buddhist temple (wat) in Samphanthawong district, the Chinatown area of the Thai capital Bangkok. Probably dating to the early Rattanakosin period, it was previously known as Wat Sam Chin (วัดสามจีน) and received its current name in 1940. Today, the temple is best known for the golden Buddha statue enshrined there. It also houses the Yaowarat Chinatown Heritage Center.
