"My Destiny" is a pop song performed by American Idol season 5 contestant Katharine McPhee and written by Harry Sommerdahl, Hanne Sørvaag, and Tim Baxter.

It was released as a CD single on June 27, 2006, with a cover of Eva Cassidy's unique 1996 version of "Somewhere Over the Rainbow" as the B-side.

McPhee's rendition of "Somewhere Over the Rainbow" was originally performed during the top 3 finalists' judge's choice round, chosen by Simon Cowell.

The judges had high praise for McPhee's performance, and it is believed that the song was responsible for vaulting her into the season's final two.

This reflects the fact that McPhee's rendition of "Somewhere Over the Rainbow" has become her signature performance, just as it was for Eva Cassidy.
