Shakeel Badayuni was an Indian Urdu poet, lyricist, and songwriter in Hindi films. After joining Aligarh Muslim University in 1936, he started participating in inter-college, inter-university mushairas and won frequently. In 1940, he married Salma, who was his distant relative and had been living in a common house with him since childhood, however, the purdah system was vogue in their family and they were not close.

Shakeel moved to Bombay in 1944, to write songs for films. He met film producer, A.R. Kardar and music composer, Naushad Ali, who asked him to sum up his poetic skills in one line. Shakeel wrote, Hum Dard Ka Afsana Duniya Ko Suna Denge, Har Dil Main Mohabbat Ki Ek Aag Laga Dengey. Naushad immediately retained him for Kardar's film, Dard (1947). The songs of Dard proved to be very successful, especially Uma Devi (Tun Tun)'s Afsana Likh Rahi Hoon. Only a few are so lucky that they attain success in their first film, but Shakeel deserved success which started with Dard and continued on over the years.

His lyrics for the song Husnwale Tera Jawab Nahin and Ravi's music score both won Filmfare Awards for the hit film Gharana. His other notable film with Ravi is Chaudhvin Ka Chand (1960), while Sahib Bibi Aur Ghulam (1962) is his biggest hit with Hemant Kumar. The title song from Chaudhvin Ka Chand, rendered by Mohammed Rafi, won Badayuni the Filmfare Award for Best Lyricist in 1961.

Shakeel penned numbers for around 89 films. In addition, he wrote many popular ghazals sung by Begum Akhtar, and which are still sung by vocalists like Pankaj Udhas and others.

The Indian Government had honored him with the title Geet Kar-e-Azam.
