Wat Pho (, ), also spelled Wat Po, is a Buddhist temple complex in the Phra Nakhon District, Bangkok, Thailand. It is on Rattanakosin Island, directly south of the Grand Palace. Known also as the Temple of the Reclining Buddha, its official name is Wat Phra Chetuphon Wimon Mangkhalaram Rajwaramahawihan (; ). The more commonly known name, Wat Pho, is a contraction of its older name, Wat Photaram (; ). The temple is first on the list of six temples in Thailand classed as the highest grade of the first-class royal temples. It is associated with King Rama I who rebuilt the temple complex on an earlier temple site. It became his main temple and is where some of his ashes are enshrined. The temple was later expanded and extensively renovated by Rama III. The temple complex houses the largest collection of Buddha images in Thailand, including a 46 m long reclining Buddha. The temple is considered the earliest centre for public education in Thailand, and the marble illustrations and inscriptions placed in the temple for public instructions has been recognised by UNESCO in its Memory of the World Programme. It houses a school of Thai medicine, and is also known as the birthplace of traditional Thai massage which is still taught and practiced at the temple.

The date of the construction of the old temple and its founder are unknown, but it is thought to have been built or expanded during the reign of King Phetracha (1688–1703). The southern section of Wat Pho used to be occupied by part of a French Star fort that was demolished by King Phetracha after the 1688 Siege of Bangkok. After the fall of Ayutthaya in 1767 to the Burmese, King Taksin moved the capital to Thonburi where he located his palace beside Wat Arun on the opposite side of the Chao Phraya River from Wat Pho. The proximity of Wat Pho to this royal palace elevated it to the status of a wat luang ('royal monastery'). In 1782, King Rama I moved
