Anirudh Ravichander (born 16 October 1990), also credited mononymously as Anirudh, is an Indian music composer, music producer, singer who works in the Indian film industry, primarily in Tamil films. He is the son of actor Ravi Raghavendra and the nephew of Rajinikanth.

Anirudh Ravichander made his debut as a music composer in his cousin Aishwarya R. Dhanush's directorial debut 3, starring Dhanush. While pursuing his degree at Loyola College, he had done background scores for the short films made by Aishwaryaa and his work on short films convinced her to have him work on her first commercial venture.^[14] In early November 2011, a leaked version of a song from the film Why This Kolaveri Di!, circulated online and the film's team decided to subsequently release it officially. It instantly became popular on social networking sites for its quirky Tanglish lyrics.^[15] Soon, the song became the most searched YouTube video in India and internet phenomenon across Asia.^{[16][17][18][19]} The song revolves around the film's main actor being dumped by his girlfriend; the song is sung by the character in a drunken state, with many of the lines nonsensical. According to the composer, 3's director Aishwarya R. Dhanush wanted a light-hearted song about failed love. Ravichander quickly composed the tune in about 10 minutes.^[19][20]
