Taipei Economic and Cultural Office in San Francisco (TECO-San Francisco, Chinese: 駐舊金山臺北經濟文化辦事處; pinyin: Zhù Jiùjīnshān Táiběi jīngjì wénhuà bànshì chǔ) represents the interests of Taiwan in the western United States, functioning as a de facto consulate.

It also oversees Cultural Centers in Chinatown, San Francisco and Milpitas, California.

[2][3] Following the signing of the Joint Communiqué on the Establishment of Diplomatic Relations between the United States and the People's Republic of China which resulted in the United States terminating diplomatic relations with the Republic of China, the consulate of the Republic of China in San Francisco was closed on 28 February 1979.

On 30 April 1992, it was renamed the San Francisco Office of the North American Affairs Coordinating Committee before it was finally renamed the Taipei Economic and Cultural Office in San Francisco on 10 October 1992.

[7] After renovations had completed on 17 October 2024, the office with its consular, economic, education and tourism division were all relocated to the fully owned, brand new building.
