Thawi Watthana (Thai: ทวีวัฒนา, in Thai pronounced as /tʰā.wīː wát.tʰā.nāː/) is one of the 50 districts (khet) of Bangkok, Thailand. Its neighbor, clockwise from north, are Bang Kruai district of Nonthaburi province, Taling Chan, Bang Khae, and Nong Khaem Districts of Bangkok, Sam Phran and Phutthamonthon of Nakhon Pathom province.
The district is named after Khlong Thawi Watthana, a very long khlong (canal) that runs roughly northwest–southeast through the area. It was a tambon, part of Taling Chan district of Thonburi Province in 1933. It was promoted to a district effective 6 March 1998.
The district is divided into two sub-districts (khwaeng).
