Lost Indulgence (Chinese: 秘岸; pinyin: mì àn) (also known as Lost, Indulgence or Lost·Indulgence) is a 2008 Chinese film directed by Zhang Yibai and written by Zhao Tianyu. Like Zhang's earlier film, Curiosity Kills the Cat, Lost Indulgence takes place in the central Chinese city of Chongqing.

The film is a family drama about the relationship between a mother and son (Jiang Wenli and Tan Jianci) after the sudden death of the father (Eric Tsang).

Lost Indulgence navigated a complicated series of schedules and cancellations before it was allowed to screen abroad, at the Tribeca Film Festival in April 2008.
