Wat Phleng (Thai: วัดเพลง, pronounced [wát pʰlēːŋ]) is a district (amphoe) of Ratchaburi province, western Thailand.

Later in 1914 the government moved the district office of Maenam Om to Tambon Pak Tho, which was more accessible as it was near the railway station.

The old central area was made the Wat Phleng minor district (king amphoe).

[2] Neighboring districts are (from the southwest clockwise) Pak Tho and Mueang Ratchaburi of Ratchaburi Province and Bang Khonthi and Amphawa of Samut Songkhram province.

Wat Phleng is divided into three subdistricts (tambons), which are further subdivided into 28 administrative villages (mubans).
