Sa Re Ga Ma Pa Challenge 2007 is an Indian television singing competition that premiered on 4 May 2007 and ran until 13 October 2007. It is the 2nd instalment of the "Sa Re Ga Ma Pa Challenge" series and the 4th public voting competition in the "Sa Re Ga Ma Pa" series. Chronologically, the show is preceded by Sa Re Ga Ma Pa L'il Champs, however systematically it is followed by Sa Re Ga Ma Pa Challenge 2005. The show features two of the previous mentors, Himesh Reshammiya and Ismail Darbar, and two new mentors to the Challenge series, Bappi Lahiri and Vishal–Shekhar. Shaan did not return to host and was replaced by Aditya Narayan, son of playback singer, Udit Narayan.

The new logo is significantly different from the 2005 logo. It features headphones on a globe to represent itself as an international competition, instead of a previous logo consisting of a portrayal of a duet singing.

On 13 October at the Grand Finale, the show broke voting records with a collection of 10,61,44,354 (10.6 crores or 106 million) votes worldwide from 181 countries. In the final tally Aneek Dhar was declared the winner with 3,65,89,134 votes, Raja Hasan as the 1st runner-up with 3,52,40,963 votes and Amanat Ali as the 2nd runner-up with 3,43,14,257 votes.

Gharana selection The Gharana (literally "House") is utilised similarly to a House system used in schools and colleges. The contestants of the gharanas have been chosen by the mentors themselves.

Two of the four previous gharanas that were featured on Sa Re Ga Ma Pa Challenge 2005 have been replaced – Aadesh Shrivastava's Jai Ho and Jatin–Lalit's Dum have now been replaced with "Josh" and "Hit Squad". The following list represents the initial 32 contestants who were chosen by the mentors and in the order they were introduced.
