Smile Angel Foundation (Chinese: 嫣然天使基金; pinyin: Yānrán Tiānshǐ Jījīn; sometimes Yanran Angel Foundation) is a Beijing-based charity founded in 2006 by Li Yapeng and Faye Wong to help Chinese children born with clefts.

The foundation is named after the couple's daughter, Li Yan, who was born in the same year with severe clefts and underwent corrective surgery in the United States.

Since 2008, the charity has worked with eight urban hospitals to make an annual journey to remote areas of China, providing free operations to children of poor famililies.

[7] In April 2010, it was recognized by the Chinese Ministry of Civil Affairs as one of the 20 most influential charity projects in 2009.

It will offer free surgeries to 600 children with cleft lip each year.
