Wat Intharam Worawihan, also commonly known in short as Wat Intharam (Thai: วัดอินทารามวรวิหาร, วัดอินทาราม) is a third-class royal temple in the area of Bang Yi Ruea, Thon Buri District, Bangkok.

It was restored by King Taksin, who afterwards granted it the status of a royal temple.

It was his favourite temple, where he came to stay overnight to meditate and observe religious precepts.

It retained its status as a royal temple throughout the King Rama I's reign (1782–1809), with three high ranking monks governing the monastery.
