Mueang Sing is a historical park in the Sai Yok district, Kanchanaburi province, Thailand, at 14°2′25″N, 99°14′29″E. The remains of two Khmer temples date to the 13th and 14th century. It was declared a historical park in 1987.

Built in the Bayon style, the temple relates to the Khmer kingdom in the reign of King Jayavarman VII (1180 to 1219). A stone inscription of Prince Vira Kumara praising his father, 23 cities are named. One of these cities was named Srichaiya Singhapura, which some scholars identify with Mueang Sing.

The name Mueang Sing first showed in the chronicles of the reign of King Rama I (1782-1809), when it was a fortified town protecting the town Kanchanaburi. In the reform of provincial administration at the end of the 19th century its status was reduced from Mueang to Tambon (commune).

Four monuments are existing inside the area of 736,000 m² enclosed by a laterite wall. The southern wall winds along the Kwae Noi river course, while the other three sides are quadratic. The main monument is in the center of the area, northwest of this is are the foundations of a second temple building. The other two monuments are of much smaller scale.
