Misteri Dilaila (transl. The Mystery of Dilaila) is a 2019 Malaysian Malay-language psychological horror thriller film directed by Syafiq Yusof. The film follows a couple as the wife goes missing after the husband experiences strange events during their first night staying at the family bungalow in Fraser's Hill. Things get complicated when another woman appears and claims to be the wife.

The film was released in two versions on 21 February 2019 in Malaysia, Singapore and Brunei, making it to be the first Malaysian film to have two versions that has different alternate endings. The movie is an adaptation of the 1986 TV movie Vanishing Act which itself was based on the 1958 movie Chase A Crooked Shadow.
