The Cave of the Silken Web (traditional Chinese: 盤絲洞; simplified Chinese: 盘丝洞; pinyin: Pan Si Dong) a.k.a. Journey to the West - the Spiders Cave (西遊記-盤絲洞; 西游记-盘丝洞) a.k.a. Spiders is a 1927 Chinese film directed by Dan Duyu and starring Yin Mingzhu as the first spider spirit. It is based on an episode of the shenmo fantasy novel Journey to the West, a Chinese literary classic written in the Ming Dynasty.

The ten-reel silent film was produced by Shanghai Yingxi Company.It was thought to be a lost film, until 2011, when an original copy of The Cave of the Silken Web was discovered in the archives of the National Library in Mo i Rana, Norway. The film was presented at the Films from the South 2013 festival in Oslo. Roughly three-quarters of the film is preserved, the first reel and a section in the middle is lost. The Norwegian copy has retained the original Chinese intertitles, but includes additional jokes in Norwegian written for the local audience.
