Mohammed Rafi ( December 24, 1924 – July 31, 1980), was an Indian playback singer whose career spanned four decades. Rafi sang in many Indian languages including Hindi, Urdu, Bhojpuri, Punjabi, Bengali, Marathi, Sindhi, Kannada, Gujarati and Telugu. He also recorded English and Persian songs. He is primarily remembered, however, for his Hindi-Urdu songs. He was the leading male singer in the Bollywood music industry from the 1940s to the 1980s.

Rafi was born the youngest of six sons of Hajji Ali Mohammad at Kotla Sultan Singh (or Kotla Sultanpur), a town near Amritsar in Punjab (British India). Rafi, whose nickname was Pheeko, started singing by imitating chants of a fakir in his village.In 1935-36, Rafi's father shifted to Lahore, and the rest of the family followed later. Rafi's family owned a men's salon in Lahore's Noor Mohalla. It was his brother-in-law Mohammed Hameed who spotted the talent in Rafi and encouraged him. Rafi learnt classical music from maestros Ustad Bade Ghulam Ali Khan, Ustad Abdul Wahid Khan, Pandit Jiwanlal Matto and Firoze Nizami.

Rafi's first public performance came at the age of 13, when he was allowed to sing at a concert featuring the legendary K. L. Saigal. In 1942, Rafi, under Shyam Sunder, made his debut as a playback singer in the duet "Soniye nee, Heeriye nee" with Zeenat Begum in the Punjabi film Gul Baloch (the film was released in 1944).In that same year, Rafi was invited by All India Radio Lahore station to sing for them.
In the 1970s Kishore Kumar's popularity increased due to the songs he sang for the film Aradhana (1969). The music for Aradhana was composed by S. D. Burman, and he had used Rafi as the male playback voice for the first two recorded duets, "Baaghon Mein Bahaar Hai" and "Gunguna Rahen Hain Bhanwre". After these two recordings, S. D. Burman fell ill and his son and assistant, R. D. Burman, took over the recordings. R. D. Burman got Kishore Kumar to sing the solos "Roop Tera Mastana" and "Mere Sapnon Ki Rani", which led to Kishore Kumar's popularity. During 1971-1973, Rafi's musical output decreased; however, he did deliver several hits. Some of Rafi's popular songs of the early 1970s were with music directors like Laxmikant Pyarelal, Madan Mohan, R. D. Burman and S. D. Burman. These include "Yeh Duniya Yeh Mehfil" from Heer Ranjha (1970), "Jhilmil Sitaron ka" from Jeevan Mrityu (a duet with Lata Mangeshkar, 1970), "Gulabi Aankhen" from The Train (1970), "Yeh Jo Chilman Hain" and "Itna to Yaad Hain Mujhe" from Mehboob Ki Mehndi (1971), "Chura Liya Hain Tumne" from Yaadon Ki Baarat (a duet with Asha Bhosle, 1973), "Tum Jo Mil Gaye Ho" from Hanste Zakhm (1973), and "Aaj mausam bada beimaan hai" from Loafer (1973).

Rafi made a comeback as a leading singer in the mid-1970s. In 1974, he won the Film World magazine Best Singer Award for the song "Teree Galiyon Mein Na Rakhenge Qadam Aaj Ke Baad" (Hawas) composed by Usha Khanna. In 1977, he won both Filmfare Award and the National Award for the song "Kya Hua Tera Wada" from the movie Hum Kisi Se Kum Nahin, composed by R. D. Burman. Rafi sang for Rishi Kapoor in films like Amar Akbar Anthony (1977), Sargam (1979) and Karz (1980). The qawwali "Pardah Hai Pardah" from Amar Akbar Anthony (1977) was a superhit. Rafi's notable renderings in the late 1970s and early 80s include Laila Majnu (1976), Apnapan (1978), Qurbani, Dostana (1980), The Burning Train (1980), Naseeb (1981), Abdullah (1980), Shaan (1980), and Asha (1980).

On Thursday, July 31, 1980, Rafi died at 10:50 p.m., following a massive heart attack. His last song was "Shaam phir kyun udaas hai dost" (Aas Paas), which he had recorded with Laxmikant-Pyarelal several hours earlier.He was survived by four sons (Saeed Rafi, Khalid Rafi, Hamid Rafi, Shahid Rafi), three daughters (Parveen, Nasreen, Yasmin) and 18 grandchildren.

Rafi's song from the film Gumnaam (1966), "Jaan Pehechan Ho", was used on the soundtrack of Ghost World (2001). The film opens with the lead character dancing around in her bedroom to a video of Gumnaam.His "Aaj Mausam Bada Beiman Hai" is featured in the 2001 film Monsoon Wedding. Several of Rafi's unreleased songs will be used for an upcoming film titled Sorry Madam. Also, his song "Haye re duniya" from Zaneet (1945) was re-mixed and used as the theme for the 2009 film Gulaal.

A documentary about Rafi’s life is under production by The Films Division of India.

In the summer of 2008, the City of Birmingham Symphony Orchestra released a double CD entitled Rafi Resurrected comprising 16 songs by Rafi. Bollywood playback singer Sonu Nigam provided the vocals for this project and toured with the CBSO in July 2008 at venues including the English National Opera in London, Manchester's Apollo Theatre and Symphony Hall, Birmingham.On September 22, 2007 a shrine to Rafi designed by artist Tasawar Bashir was unveiled in Birmingham. Bashir is hoping that Rafi will attain sainthood as a result.

Both Rafi and Lata Mangeshkar are mentioned in Cornershop's homage to Indian playback musicians, "Brimful of Asha".

Rafi's funeral procession was recorded on a very rainy day in Mumbai. A portion of that same recording has been used in one of the Hindi movie released later. It was one of the biggest funeral processions Mumbai had ever witnessed, with over 10,000 people attending.

The Padma Shri Mohammed Rafi Chowk in the Bandra suburb of Mumbai is named after Rafi.
