Wat Yansangwararam Woramahawihan or Wat Yan (Thai: วัดญาณสังวรารามวรมหาวิหาร, RTGS: Wat Yannasangwararam, pronounced [wát jāːn.nā.sǎŋ.wá(ʔ).rāː.rāːm] ) is located in Huai Yai in the Chonburi province of Thailand. It is a large Buddhist temple complex with gardens and lakes and has been under the patronage of Bhumibol Adulyadej. Most of the buildings at Wat Yansangwararam were erected in honor of the Thai Royal Family. The temple is a replica of the Mahabodhi Temple in Bodh Gaya, Bihar, India.

International pavilions with ornaments around the adjacent lake and statues of revered monks, also of Bhumibol Adulyadej and his mother Srinagarindra, the Royal Grandmother, in the middle of parks offer the opportunity to walk for hours and study.

The monastery Wat Yansangwararam, which only was built in 1976 by Vajirañāṇasaṃvara or Somdet Phra Nyanasamvara, the 19th Supreme Patriarch of the Thai Sangha for Dharma practice, especially for Samatha and Vipassana, is an important center of the Dhammayuttika Nikaya in Thailand. The project started up on initial 16.01 hectares (39.6 acres) donated by Dr. Kajorn and Khun Ying Nithiwadee Ontrakarn. Additional land in the area has been purchased by members of the building committee and devout supporters of Somdet Phra Nyanasamvara.
