Wat Chantharam (Thai: วัดจันทาราม) also colloquially known as Wat Tha Sung (วัดท่าซุง) is an ancient Buddhist temple in Uthai Thani province.

The temple built in the Ayutthaya period, coinciding with the Narai's reign. In those days, there were a lot of logs being transported in front of the temple on the Sakae Krang river. Hence, this temple is also familiarly known as Wat Tha Sung in which Tha (ท่า) means "pier" and Sung (ซุง) means "log" in Thai.

The temple has been getting old and dilapidated according to the period. Until the year 1968, when Luang Phor Lersi Lingdam became an abbot. Therefore, the temple has been developed continuously. Luang Phor Lersi Lingdam was a monk who was widely respected by Buddhists as an expert in Vipassana practice.
