Insan Jaag Utha (lit. 'Mankind has awoken') is a 1959 Hindi-language social drama film, produced and directed by Shakti Samanta, and written by Nabendu Ghosh and Vrajendra Gaur, based on a story by Saroj Mitra. The film stars Madhubala, Sunil Dutt, Nasir Hussain, Bipin Gupta and Madan Puri in lead roles. It has music by Sachin Dev Burman, with lyrics by Shailendra.

Gauri lives in a small village in India with her crippled ex-army-man and freedom fighter dad, Laxmandas, and a younger brother, Gulab, and makes a living working as a laborer. One day she notices a man lurking around their house, this man subsequently introduces himself as Ranjeet, who has just arrived from Bombay. Ranjeet and Gauri become friends after he treats a wound on Gauri's foot, and then both fall in love with each other. Ranjeet starts working for the Government which is in the process of building a dam, where Gauri also works. Ranjeet starts work as a laborer also, but is subsequently promoted as a crane operator. What Gauri and Laxmandas do not know is that Ranjeet is in this village for a reason - greed for the suitcase of gold that he himself had buried in Gauri's front-yard - the very same gold that he was caught smuggling five years ago and the very same gold that he had spent five years in prison for.

Early in his career, Samanta had directed only crime thrillers including Inspector (1956) and Howrah Bridge (1958). A few days after the success of Howrah Bridge (1958), which was directed and also produced by him, he began working on Insan Jaag Utha. Insan Jaag Utha was a film with social and patriotic themes, and this was an attempt by Samanta to shift to making social films.^[2] A large part of the film was shot on location at the Nagarjuna Saagar Dam, and the whole crew stayed in several guest rooms situated near the dam.^[1]

The soundtrack of the film was composed by S. D. Burman, with lyrics by Shailendra. It is noted for the duet Jaanu Jaanu Ri sung by Asha Bhosle and Geeta Dutt, which was shot on location at the under-construction Nagarjuna Sagar Dam.
