Sukhwinder Singh (born 18 July 1971) is an Indian Bollywood playback singer. Singh is famous for singing "Chaiyya Chaiyya" for which he won the Best Male Playback Award at the 1999 Filmfare Awards. The song, from Mani Ratnam's 1998 film Dil Se.., was composed by A. R. Rahman, written by Gulzar, and sung in duet with Sapna Awasthi. It was also featured in the musical Bombay Dreams and, in remixed arrangements, in the titles and credits segments of Spike Lee's 2006 film, Inside Man. Singh later gained more international fame for singing "Jai Ho" from the film Slumdog Millionaire, which won an Academy Award for Best Original Song and a Grammy Award for Best Song Written for a Motion Picture, Television or Other Visual Media. His rendition for the 2014 released film Haider fetched him the National Film Award for Best Male Playback Singer.

Singh comes from a very poor household. His mother was a teacher and his father was a struggling singer in Amritsar, Punjab. His parents struggled to make ends meet. Nonetheless, Singh was very passionate about his singing career that he used to lock himself in a room for long hours and did his practices.

In his struggling years, he moved to Mumbai in his early years and worked for laskhmi pyare lal. However, the producers and directors kept him in the background. Having said that, Singh got his break in the movie Karma, in which he sang a few lines; then he sang hit song "Aa ja Sanam" in film Khilaaf. But he wanted to finetune and enhance himself as a singer/performer, so he took a sabbatical and left Mumbai to tour England and America to see, hear and understand various forms of music. After this broadening of his musical horizons, he returned to Mumbai to kick-start his musical career.

His first effort in Hindi films, Aaja Sanam, went largely unnoticed, even though the music carried the names of Laxmikant-Pyarelal. Then for Dil Se... A. R. Rahman used Sukhwinder for "Chaiyya Chaiyya". The other films that followed – including Taal, Biwi No. 1, 1947 Earth, Daag, Jaanwar, Dillagi, Moksha, Thakshak, Tere Naam, Apna Sapna Money Money, Shadi Se Pehle, Shabd, Chak de! India, Om Shanti Om and Black and White- that have made him a household name.

Of these, "Chaiyya Chaiyya" from Dil Se.., "Dard-E-Disco" from Om Shanti Om, "Chak De India" from Chak De! India, "Haule Haule" from Rab Ne Bana Di Jodi, "Marjaani" from Billu and "satak le" from Happy New Year have become certified hits.
