Watthana or Vadhana (Thai: วัฒนา, pronounced [wát.tʰā.nāː]) is one of the 50 districts (khet) of Bangkok, Thailand. Neighbouring districts are (from the north clockwise): Ratchathewi, Huai Khwang, Suan Luang, Phra Khanong, Khlong Toei, and Pathum Wan.

Watthana became a separate district by splitting from Khlong Toei in 1998 to provide better service to its population. The district obtained its name from Princess Galyani Vadhana, the elder sister of King Bhumibol Adulyadej. Watthana or Vadhana means 'development'. The area is among the most developed parts of Bangkok.

On 1 January 2009, Watthana was the location of the Santika Club fire, which killed 66 and injured 222.

The district is divided into three sub-districts (khwaeng), from west to east:

They are all named by adding Nuea, meaning North, to the corresponding subdistricts in Khlong Toei district.

Encompassing the area between Sukhumvit Road and Khlong Saen Saep, Watthana is one of the commercial districts in Bangkok, with many condominiums and hotels. Expatriates of many nationalities reside there.

The lotus shape is supposed to be an offering to pay respect to the princess.^[2]
