The Fanglan Mansion (traditional Chinese: 芳蘭大厝; simplified Chinese: 芳兰大厝; pinyin: Fānglán Dàcuò) is a historical house in Da'an District, Taipei, Taiwan.

The mansion was built in 1806 by Chen's family as their first house when they immigrated from Anxi County, Fujian.

The mansion was constructed from local stones with fir wood and bricks shipped from Mainland China. A waterwheel attached to one of the exterior walls was decorated with clay moldings. The original layout of the mansion was a traditional three-sectioned structure with left and right wings. Those two wings have since collapsed and no longer exist.

The mansion is accessible within walking distance east of Gongguan Station of Taipei Metro.
