"Let Me Be Your Star" is an original song introduced in the first episode of the first season of the musical TV series Smash, entitled Pilot. It was written by Marc Shaiman and Scott Wittman, but in the show's universe, it was written by songwriting duo Tom Levitt (Christian Borle) and Julia Houston (Debra Messing) for the Marilyn Monroe musical they are working on, Bombshell.

In the first episode, the song is performed by characters Karen Cartwright (Katharine McPhee) and Ivy Lynn (Megan Hilty) as they each prepare for and then audition for the role of Marilyn in front the production team.

The song has since been reprised numerous times in various episodes, both as solos and duets. For the first season, it was also sung by Karen and Ivy in the second episode "The Callback" and the seventh episode "The Workshop", by Ivy in the sixth episode "Chemistry", and by Rebecca Duvall (Uma Thurman) in the eleventh episode "The Movie Star" and the fourteenth episode "Previews". In the second season, it was reprised by Karen and several female members of the Bombshell ensemble in the first episode "On Broadway", and by Ivy in the eighth episode "The Bells and Whistles" and the eleventh episode "The Dress Rehearsal".

The song was originally released as a single to digital music retailers and is available on the cast albums The Music of Smash and Bombshell (the latter with an extended intro not heard on the show), with McPhee and Hilty's vocals from the "Pilot" episode.
