Phra Phutta Trai Rattana-nayok, i.e. the principal Buddha statue at the main wihaan of Wat Kanlayanamit Woramaha-wihaan in Thonburi's Kuti Jihn district, is circa 15.15 metre tall and seated in the bhumisparsa pose.

King Rama III had it cast after the 19 meter tall gilded Buddha of Wat Phanan Choeng in Phra Nakhon Sri Ayutthaya (fig.), in May 1837. It is also known as Luang Pho Toh, as well as by its Chinese name Sampokong (ซำปอกง). It was for a long time the tallest seated Buddha image in the capital, until this record was broken in mid-2020 by the conclusion of the giant 69 metre tall Phra Phutta Thammakaya Thep Mon Buddha image (fig.) of Wat Pahk Nahm Phasi Chareun, on which construction had started in 2017.
