Rajendra Krishan was a poet, screenwriter and lyricist in the Hindi film industry. Born in Jalalput Jattan, Gujrat district (now in Pakistan), he moved to Mumbai in the mid 1940s to become a screenwriter. His debut as a screenwriter and lyricist was for the film "Janta" (1947) and his hit came a year later for "Aaj Ki Raat" (1948).

When Mahatma Gandhi was assassinated, Rajendra Krishan wrote the non-film song "Suno Suno Aye Duniyawalon Bapu Ki Yeh Amar Kahani". The song, composed by Husnlal - Bhagatram and sung by Mohammed Rafi, became popular across the country and helped boost Rafi's career. "Lahore" and "Badi Bahen", both released in 1949, also were very successful. Although Rajendra Krishan wrote more more than 250 films in a career spanning four decades, he somehow did not get the attention accorded to some of his peers. This despite hits like "Anarkali" (1953), "Naagin" (1954), "Adalat" (1958) and "Padosan" (1968).

Rajendra Krishan worked with all major music directors of his time including Shankar - Jaikishan, S.D. Burman, R.D. Burman, Salil Chowdhury, Chitragupt, Laxmikant - Pyarelal, Madan Mohan, Hemant Kumar, and C. Ramachandra, with whom he formed a notable partnership.

In 1965, he won the Filmfare Award for the Best Lyricist for the song "Tumhi Mere Mandir" ("Khandaan", 1965).
