The film, directed by Abhishek Kapoor, is said to be a love story that unfolds in the course of a pilgrimage.
The project is being produced by KriArj Entertainment, T-Series, Guy In The Sky Pictures in association with Balaji Motion Pictures.
"With blessings of Shiva... Kedarnath to release on 21st Dec 2018," tweeted the official twitter handle of KriArj Entertainment.
The shooting for the film had recently been shifted to Mumbai after the completion of a month-long schedule in the holy lands of Kedarnath.
The makers of the film had last month revealed the first look of Sara Ali Khan, who is the daughter of actor Saif Ali Khan and Amrita Singh.
