Wat Ratchaburana Ratchaworawihan (Thai: วัดราชบุรณราชวรวิหาร) or usually shortened to Wat Ratchaburana (วัดราชบูรณะ), commonly known as Wat Liap (วัดเลียบ), is a second-class temple in Maha Nikaya sect of Buddhism, located at 119 Chakkraphet Road, Wang Burapha Phirom Subdistrict, Phra Nakhon District, Bangkok at the foot of the Memorial Bridge near Pak Khlong Talat and Praisaniyakarn, diagonally from the Long Corridor of Suankularb Wittayalai School.

The temple was built in the late Ayutthaya period by wealthy Chinese merchant named "Liap" (เลี้ยบ).

Later, Phra Khuna Charawat (พระคุณาจารวัตร) the then abbot and local people helped to rebuild the temple.

The present ubosot (ordination hall) was built in 1960, The most outstanding building of this temple is the prang (Khmer-style pagoda), which was built in the reign of King Rama III and restored in 1962 and again in 2007 by the Metropolitan Electricity Authority (MEA).

Apart from the beautiful tradition architectures and Buddha images, the highlight is the wall paintings inside the ubosot, which is the work of Khrua In Khong (ขรัวอินโข่ง), a monk and a talented artist who lived during the reign of King Rama IV.
