Anoushiravan Rohani (b. 24 July 1939) is an Iranian pianist and composer, known for composing and conducting contemporary classical music as well as pop music with a light-classical leaning. Over a prolific career he has written more than 500 compositions, including vocal, orchestral, and piano works, as well as a number of Iranian film scores.

Rohani’s most popular composition, “Soltane Ghalbha” (“Emperor of Hearts”), was written for the title song of the 1968 Iranian film of the same name and became one of the best-loved songs in Iranian popular music, later arranged for classical guitar. He is also credited with composing the widely used Persian version of “Happy Birthday,” “Tavalodat Mobarak.”
