Nidra (Malayalam: നിദ്ര) is a 2012 Indian Malayalam-language romantic thriller film directed by Sidharth Bharathan in his directorial debut. A remake of the 1981 film of the same name directed by Sidharth's father Bharathan, it stars Sidharth Bharathan alongside Rima Kallingal and Jishnu in the main roles. It marks the second collaboration of Jishnu and Sidharth after Nammal and comeback of Jishnu Raghavan Sidharth co-wrote the adapted screenplay with noted author Santhosh Echikkanam. The songs were composed by Jassie Gift and the background score was by Prashant Pillai. The cinematography was handled by Sameer Thahir.

Considered to be a part of the new-wave in Malayalam cinema, Nidra narrates the sensuous love story of Raju (Sidharth) and Ashwathy (Rima Kallingal). Raju is driven to the brink by circumstance and expectations of a materialistic world. The only person who keeps him grounded is his wife, Ashwathy. The film was well received by critics but did not fare well at the box office, mainly due to lack of promotion.
