Tjong A Fie Mansion (traditional Chinese: 張耀軒 故居; simplified Chinese: 张耀轩 故居; pinyin: Zhāng Yàoxuān Gùjū) is a two-story mansion in Medan, North Sumatra, built by Tjong A Fie (1860–1921) a Hakka merchant who came to own much of the land in Medan through his plantations, later becoming 'Majoor der Chineezen' (leader of the Chinese') in Medan and constructing the Medan-Belawan railway.
Tjong A Fie is said to be related to Cheong Fatt Tze, who built the Cheong Fatt Tze Mansion in Penang, Malaysia.
The building is constructed in Chinese-European-Art Deco style, and was completed in 1900, and said to have been modeled on the Cheong Fatt Tze Mansion
